Updated review:
Much better on the reread because it was less confusing. Reading the glossary and Cohort files before starting was very helpful and I wish they'd been at the start of the book. 

Previous review:
3.5 stars because it took over halfway through the book to get me invested in the story. Good mystery and story once it got going though! I'm not one to say this usually, but I think I would have rather watched a movie of this. Tentatively interested in the sequel because Harrow's an interesting character.
