 Flynn's girlfriend is missing, and as one of her closest friends and the last person to see her before her disappearance, the police as sure that Flynn is hiding something. And he is- but it's all a lot more complicated than you'd expect. As it turns out, Flynn and January had started to drift apart recently and they didn't know each other as well as they used to- each of them had secrets, and now Flynn is the only one around to set the record straight. Determined to find her, hoping that it's not too late, Flynn must face his own truths as he seeks the truths that January was trying so desperately to hide. 
 Well-plotted mystery with plenty of surprises dovetails nicely with some dark surprises from January's world and some satisfying emotional truths from Flynn's.
