I decided to read this book after seeing an email from Audible. It sounded intriguing, and I like a good science fiction book with wormholes, folds in space, etc. And I enjoyed the first half of it. And then 50% into the book! it took a hard left turn and just about lost me. I really only finished it because I kept hoping it would get back on track. Unfortunately it didn't work out. By the end I felt ripped off, like I'd watched a bad made for TV movie on SyFy. 2.5 stars because I liked the first half of the book a lot.
