This book takes place two years after the events of the previous books in the 1-800-WHERE-R-YOU series. Protagonist Jess has matured a lot and Missing You finds her in a darker place than we've seen her before. After working for the US Government in Afghanistan, using her psychic abilities to find terrorists, she has seen the horrors of war first hand, and has returned to the States broken. Nightmares plague her sleep, and since she can't sleep, she can't find missing people -- her "gift" is gone, as quickly as it came.

She has also broken up with Rob Wilkins, the hero of the preceding books, because she saw him kissing another woman at his garage. Reeling from the trauma of war and the heartbreak of losing Rob, Jess went to New York to live with her best friend Ruth while they both attend Julliard. While Jess has been very successful in her studies there, she isn't happy: she doesn't want to be a concert musician, but she doesn't know what she wants instead.

Jess's life is plunged even further into uncertainty when Rob shows up at her apartment in NYC, looking for her help to find a sister Jess never knew he had.

The mystery of the missing sister is resolved with such ease it's anticlimactic, and the sister's recovery and dealing with the aftermath (the sister had gotten mixed up with amateur child pornographers), isn't enough of a plot to carry this book. However, Missing You is my second-favorite book in the series (after the first, When Lightning Strikes), because it's a pleasure to see Jess and Rob grow up and behave as (almost) adults. Jess has finally gotten a handle on her anger management problems and learned to use her brain rather than her fists to solve problems, and Rob is no longer the disreputable juvenile delinquent from the wrong side of the tracks, but a responsible and self-sufficient young entrepreneur. I found this a satisfying end to an entertaining (if somewhat dated and uneven) series.
