Pretty, free spirited Susan is almost fifteen, and she and her best friend Rose discover a new, thrilling world of intimacy - together, but soon with others too. There's a not so secret diary, and the question of who seduces who isn't always quite clear, but Susan keeps toeing lines and stepping past them gracefully.
When tall, handsome William poses the question, it's not what petite, inexperienced Billie expected. Yes, he wants her, but not as the partner in a fluffy romance. Yet her broken heart won't let go, even when she glimpses the darkness looming ahead. She needs to make a decision. As decisions of the heart often go, they are rarely reasonable, and sometimes insane.
