I absolutely love a missing persons story, I never seem to tire of them but I love when the missing person returns even more so this one sounded right up my alley and it was! I was hooked from the start, of course I wanted to know where Ellie had been and who had kept her for two years but I was also very invested in Chelsey as well. She was such a well developed character, really all the characters were well drawn and the way her past shaped her as a detective was so interesting and heartbreaking. This one is pretty dark and disturbing and the psychological aspects on both Ellie and Chelsey were examined in detail making for some chilling reading. There are multiple viewpoints and the audio version had a terrific cast of narrators so if you like to listen to books I can highly recommend that version. Hearing parts of this out loud gave me serious chills and made this one all the more memorable than it already was. If you want a solid and twisty suspense this was excellent.
