Hold Tight
Harlan Coben
 The story is introduced with the characters Marianne, Nash and Pietra. Pietra tricks Marianne by drugging her which leads to Nash brutally beating Marianne to death, his last words to her being: "Tell Cassandra I love her." They remove her clothes then dress her to look like a prostitute and toss her body in a dumpster (skip). The action switches to Tia and Mike Baye who never imagined they'd become spying, overprotective parent. But their sixteen-year-old son, Adam Baye has been unusually distant and aloof lately, and after the recent suicide of his classmate and closed friend, Spencer Hill, who taking vodka and tablets on his school's roof in the night to death, they can't help but worry. They install a spy program on Adam's computer and within days they are jolted by a strange message to their son from a correspondent known only as CeeJay8115: "Just stay quiet and all safe." The detective investigating Marianne's murder, Loren Muse, realizes that Marianne is not a prostitute and that someone has gone to great lengths to try to fool the authorities. However, the face of Marianne has been so badly mutilated it is impossible for anyone to identify her. Susan and Dante Loriman meet with their son's (Lucas) doctor (Mike Baye) only to be told Lucas needs a kidney transplant urgently. Neither parent is a suitable match and with some investigating, Mike finds out that Dante is not the biological father to Lucas. Meanwhile, browsing through an online memorial for her son, Betsy Hill is struck by one photo in particular that appears to have been taken on the night of Spencer's death and that he wasn't alone. She thinks it's Adam Baye standing just outside the camera's range. She confronts him and asks about the photo, but he runs away. The daughter of Marianne and Guy, Yasmin is being bullied at school because her teacher (Joe Lewiston) commented on her facial hair in front of the class. Yasmin shows her only friend Jill Baye (Mike and Tia's daughter) her father's (Guy) gun, which is already loaded and hidden in a drawer in their house. She tells Jill how she dreams of getting revenge on Mr Lewiston. Worried about the safety of their son, Mike tells Adam he must attend a hockey game with Mike's friend Mo. This is a diversion to try to avoid the party referred to in an email Mike and Tia found on their son's computer a few days earlier, the party claims that there will be alcohol and drugs served. Adam is not around when his father comes to pick him up to attend the hockey game, and Mo tells Mike how to use the GPS on Adam's phone to track him. Mike ends up following him into a very bad part of the Bronx. He starts to chase after what looks to be one of Adam's friends, but is then confronted and severely beaten by an unknown group. He winds up in hospital and still hasn't found his son. Reba Cordova is Nash's next victim, and she is likewise beaten to death, for reasons still unknown to the reader. Before killing her he also told her the same thing Nash told Marianne: "Tell Cassandra I love her." We find out Cassandra died a few years ago due to cancer, and was deeply loved by Nash. Cassandra is the sister of Joe Lewiston, and had another brother named Curtis, who was murdered in an assumed robbery. Mike's professional partner, Ilene Goldfarb, confronts Susan to find the real father of Lucas, as he could be a potential kidney donor. Susan tells her that she was raped, and that it was impossible for her to contact him to ask if he could be tested as a potential donor. Later the readers find out that the reason that her rapist cannot be contacted is because Susan had killed her attacker. She then confides that the murder was set up to make officials think the cause of the murder was most likely a robbery, this leads the reader to believe that Curtis Lewiston is the rapist. The events start to come together by the end of the book as the connections of the murders, Adam's disappearance, Spencer's apparent suicide, and the need for a good donor for Susan's son are explained, and the origin of all of the mayhem is revealed.
