So disappointing. Full disclosure: I did not make it through this book. I hung in for 3/4 of the story but I found the characters a bit flat. The plot holes and over explaining of some of the science weren’t the worst part… it felt like a bad romance novel. Two model looking people falling in love was at the center of this story, rather than a vehicle to build the characters profiles/motives. I’ve read several BA novels and have never put one down before. This is not his best work.
