Alex gave a short, amused snort at my combative expression, but this time he took the question entirely seriously. Leaning back in his chair, he turned the empty cup thoughtfully between his fingers, as though preparing not just to answer, but to deliver a proper little lecture.
“Right then, brace yourself, young vet. I’m about to shatter a few of your girlish stereotypes,” he smirked.
I snorted inwardly. Oh, absolutely. At vet school, they’d taught me to treat cows, castrate piglets, and figure out why some poor cat had decided the best way to communicate its illness was to piss in its owner’s shoe. What nobody, apparently, had thought to include in the curriculum was a module called “What to do when a nineteen-year-old werewolf who could bite through a bear’s spine sits down opposite you at your own kitchen table.”
Still, I decided not to complain. I needed information, and right now I intended to get as much of it as I could.
I wrapped my fingers tighter round my cup and forced myself not to fidget. As a child, I’d done exactly that whenever my grandmother launched into her endless tales of monsters, enchanted forests, and creatures that sensible folk gave a wide berth. I’d lean forward, forgetting everything else, hanging on every word as if my life depended on it.
Funny. Back then, I was listening to fairy tales.
Now one of those fairy tales was sitting right opposite me, drinking coffee as if it were the most natural thing in the world.
“Right, maturity then...” He paused, gathering his thoughts. “Physiologically, we mature a little earlier than humans. Around twelve to fourteen, in human years, the cubs hit a massive hormone spike, and that’s roughly when the first shift happens. The body begins to change, and the beast makes itself known. But until we’re sixteen, we’re under near-constant supervision — parents, mentors, the Alpha. Training, studying, duties. By evening, we’ve barely got enough energy left to crawl into bed. Any attempts at romance in human form are stamped out fast by the elders.”
I paused to think.
If you set aside the whole ‘shifting’ business, they weren’t actually all that different from humans. Around the same age, ordinary teenagers went through their own biological upheaval: hormones in chaos, bodies steadily morphing from child to adult. Nothing mystical. Just plain physiology.
The funny thing, though, was this. From what Alex was telling me, children in the pack grew up knowing their bodies would change, and no one pretended otherwise. In our human world — especially that part of it so fond of moralising about ‘decency’ and ‘proper upbringing’ — there seemed to be an unspoken rule that until you turned eighteen, you existed in some kind of sterile bubble. No sexual maturity, no desire, no complex physiological processes at all. According to this remarkable logic, you weren’t supposed to learn about any of it until you were eighteen either. And then — bam! — you were suddenly an adult, and all those supposedly non-existent functions miraculously appeared overnight.
I smiled faintly to myself. Looked like werewolves, at least, were more honest about nature. Their children remained children for as long as the adults deemed them so, but nobody tried to convince biology that hormones ought to observe age restrictions.
Out loud, however, I said something entirely different:
“That strict, is it?” I raised an eyebrow, gripping my cup a little tighter.
“Wait,” I interrupted, holding up a finger. “Don’t young she-wolves get pregnant from all this? If you lot have a hormone festival every year, you ought to be breeding like rabbits!”
Alex laughed, openly and without the slightest malice. The movement sent a ripple of muscle across his ribs, right over those same frightening, jagged scars, and I found myself looking at him a little longer than I had intended.
“Sasha, you’re forgetting one important thing. True mates.”
I frowned for a moment. True mates? Was that like ordinary wolves choosing a single partner and staying with them for life? Or was it something more complicated? Judging by the way Alex had said it, probably the latter.
“True mates?” I repeated. “What does that mean? Is it like when a wolf chooses one partner for life?”
“Not exactly. Though the basic idea is the same,” Alex replied. “Our physiology isn’t all that different from human physiology. But mentally, we’re still somewhat different. Theoretically, a she-wolf can conceive during the rut, but a wolf cub will only be born if it’s conceived with the partner with whom she’s formed a true bond. In both human and wolf form. And such pairs are rare. Very rare.”
I fell silent for a moment, trying to get my head around it. So it wasn’t simply a matter of choosing who she wanted to have a child with. Somehow, her own body determined whether a particular partner was compatible with her. It sounded strange, but in a world where a human could turn into a wolf, perhaps I shouldn’t have been surprised by yet another biological oddity.
“So casual flings don’t work?” I asked, trying to keep my voice as ordinary and clinical as possible.
“Exactly. Nature has provided a safeguard against unnecessary chaos.”
“Right,” I muttered, digesting what I’d heard. “So your nature is more foresighted than ours.”
I looked at him again, trying to work out whether I’d missed something. If everything really worked that way, there was one next question that seemed perfectly obvious.
“But you still haven’t answered the main question, Alex. How many partners have you had during these ... spring ruts?”
Alex raised his hands in a mock gesture of surrender. Golden flecks danced in his amber eyes, while his gaze briefly slid over my chest, making me regret once again that I hadn’t grabbed a proper towel or at least a dressing gown. But Alex seemed completely oblivious to my embarrassment.
“Three.”
“Three?” I echoed, my scientific curiosity giving way to genuine surprise for a moment.
“All in spring. No love, no promises, no grand plans. Just biology. When the instincts became too ... insistent. If you like, simply a way of relieving the tension.” He shrugged. “And getting back to your earlier question. I’ve heard that some shift back into human form and go deeper into the woods. Everyone knows perfectly well why they’ve gone there. No illusions.”
His voice grew more serious.
“But if a she-wolf were to conceive from such a union ... it’s a disgrace. For both of them. Because then it’s immediately obvious what happened and why. It’s punishable by exile. Or death. And while the men usually choose the former, the women choose the latter.”
I nearly choked. Exile or death. For an unplanned pregnancy? All right, human society isn’t exactly thrilled by such surprises either, but at least we have options: contraception and, if necessary, abortion. And even if everything else failed, we didn’t exactly send people to the stake because nature had decided to play a joke at the wrong time. Though, come to think of it, even in the Middle Ages things weren’t quite that barbaric. And punishments like that were widespread.
I fell silent for a while, turning his words over in my head again. Alex wasn’t trying to hide anything from me, at least when it came to things like this. And for some reason, that made me think harder than if he’d simply refused to answer. If he could calmly tell me about things like this, what exactly did that mean to him? And why did I even care?
“So ... three,” I repeated more quietly, studying his face. “And none of them were ... true mates?”
Alex shook his head.
“None.”
“Well, I approve of your honesty, Alex. But since we’re talking about biology ... I have a purely practical question for you, as an almost-qualified vet.”
Alex raised an eyebrow with interest and took the last sip of his coffee, reminding me once again that I really ought to stop by a shop.
“Notice,” I continued, tilting the equally empty cup, “you said that a she-wolf can only become pregnant by her true mate. But what about ... ordinary human women? Can a werewolf and a human actually have children together?”
My question made him more serious. The golden flecks in his eyes gave way to a deep, attentive gaze.
“They can, but it’s bloody rare, Sash,” he replied calmly. “Half-breeds born from such a union almost never inherit the wolf. They remain human, apart from having a somewhat stronger immune system. But the pack doesn’t like such unions. Nature itself puts up barriers. Though...” Alex suddenly smiled like a predator, that same possessive rasp returning to his voice. “What’s with the interrogation? Worried about the consequences of our night together?”
“I’m looking after my own safety,” I shot back, feeling warmth creep into my cheeks despite myself. But I wasn’t backing down. “My inner medic is sounding the alarm. Your super-immune system is all very well, but you could still be an ordinary carrier of all sorts of human diseases. Have you ever thought about that, out there in your woods? Not to mention this morning.”
Alex couldn’t help himself and let out a quiet, rolling laugh, throwing his head back.
“I have, Sash. Believe it or not, we’re not savages. Once a year, the entire pack undergoes a thorough medical examination with our own doctors. Werewolves take the purity of their blood and their health very seriously, so I’m as clean as a whistle in that respect. I could even bring you a certificate with an official stamp if that would put your mind at ease.”
“We’ll see how you behave,” I snorted. The tension had eased a little, and I decided it was time to end the interrogation before the situation got out of hand again. “Anyway, don’t get your hopes up. I’m not falling for your pheromones again.”
And then, more quietly, I muttered, looking down into my cup:
“Although nobody said anything about a repeat ... Right, forget it. I’m getting ahead of myself.”
Judging by the fleeting smile that crossed the young man’s face, he’d heard every word perfectly. Bloody werewolf. Part of me was even jealous. Sight, hearing, touch, reflexes ... It wasn’t as though I was particularly clumsy, but abilities like that ... I got up from the chair, feeling that I urgently needed to think through everything I’d just learned. There was simply too much information, along with his warmth, his scent and his confidence, crammed into my tiny kitchen. I went over to the sink, put the empty cups and the Turkish coffee pot down, turned on the tap and pretended to be completely absorbed in washing up.
Perhaps that was actually useful. While I scrubbed the cup, I could calmly sort through everything he’d just told me. True mates. The spring rut. Some strange biological protection against accidental pregnancy. Medical examinations for the entire pack. Half-breeds who almost always remained human.
I found myself thinking as I ran the sponge around the inside of the cup. If I stripped away everything supernatural, there really was a certain system to what he was telling me. Perhaps that was why I kept clinging to biological explanations. If I could find the pattern, understand the mechanism and break everything down into its component parts, what was happening stopped seeming quite so impossible.
There was just one small detail that, for some reason, didn’t fit into my calculations at all.
I’d completely forgotten that I was standing there naked.
And so was Alex.
It occurred to me the moment I felt the warmth of his body behind me, followed by his hands on my breasts. I froze, not even having time to turn my head. Alex had approached completely silently — so silently that I hadn’t heard a single footstep. So much for increasing the distance.
I swore inwardly.
