The book seems like a nice idea - a somewhat different riff on the being-pulled-out-of-time trope - that hasn't really fulfilled its potential. In a way, it is as if the book wasn't quite finished. Aside from the (way too many) typos, some parts of the story haven't been totally thought through. The main characters don't seem whole, their motivations aren't clear and they are very difficult to identify with. The two main supporting characters feel more like props than human beings.
The parts I liked best in this book were the prologue and the epilogue, which suggests that this book has potential, but perhaps requires another look by the author to make it work. I found myself wishing midway that the book would end soon.
