As I read this story, at first I found myself thinking the author was merely a different pen name for one of several authors I know. Then I started noticing the little technical flaws that would rarely make it into one of their works, so I stopped believing that and instead concluded that this was a distinct but still skilled author.
The characters are compelling and sympathetic, the storytelling is an unusual style which has some odd charm to it, the plot is tragic and poignant. I really think a lot of it as a piece of work.
That said, I didn't entirely enjoy it... it has a sad sweetness to it which isn't really to my liking, and it brought back memories of my own life, with the emotions that go with it. A sign of a skilled author, to be sure, but not necessarily one whose work has a great universal appeal.
Those who like the idea of seeing a series of vignettes into a failed relationship, and enjoy philosophical musings will find this one a gem. Those looking for happy endings - even when the unhappy ending is foreshadowed from almost the very start - will want to avoid this piece, as will those looking for stroke. Also, anyone who has a serious issue with cheating stories might want to pass this one over, as that code is applicable but missing.
