This is the book version of the theme-and-variations composition structure used in classical music and sometimes techno. The first chapter is a lovely and sad story in its own right; it almost feels like what Chekhov might have come up with if he'd been writing with today's gender and sexuality sensibility. Each thereafter takes mostly the same set of characters but with progressively larger twists - at first it's very much "what if protagonist had made a different choice at this key moment?", but it gradually shades over into wilder sci-fi speculations.

Strangely, it was the wilder variations that really made the book click for me. Before things got really weird I was starting to question how the book was going to sustain interest for 11 chapters, but North answered that question very effectively. I don't think it would have worked to go directly to those, the smaller variations feel needed for the coherency of the whole, but I loved the effect of the whole set together.
