A FANTASTIC novel. The depth, adjustment, and unique turn of all the characters just grabs you from the beginning and doesn't let you go. Honestly, Ichi's fascination and love for rabid carniverous bugs is kind of repelling and pretty darn confusing ... but in the sections focusing on only him and bugs, his reaction and emotional attachment to them, it makes sense. That's incredibly hard to do, from a writer's point of view - making something so weird seem so normal.
Rye is a charming character, well build from the ground up. The transition from Pet to [==spoiler==] is gradual and very believable.
The ending conflict came across to me as a bit anticlimactic, but then again it seemed to Rye that it was as well - something more was expected, the result harder to obtain. Sometimes things really AREN"T earth-shatteringly hard though. The last few chapters/epilogue wrapped things up beautifully, and Rye's gift to Ichi?
