This new novel by Harlan Coben is definitely suspenseful, filled with lots of puzzles. It follows various story lines that eventually all fit together. The main story line deals with Kat….a NYPD detective whose best friend signs her up for an online dating service where she finds an old boyfriend who she never got over. This one simple act, combined with the death of her father’s convicted killer, sets Kat off to question events in her past that have always remained a mystery and to seek answers she might not want to live with. Meanwhile, a young boy comes to her insisting that his mom has gone missing, even though everyone else thinks she is just away with her new boyfriend. How could all of this possibly tie together? There are many layers in this story, and the clues are expertly interwoven throughout to keep you guessing. If you like mystery and suspense, then I recommend this one!
