The Missing Half: A Novel

NEW YORK TIMES BESTSELLER • Two women haunted by their sisters’ unsolved disappearances band together in this captivating mystery from the author of All Good People Here and host of the #1 true crime podcast Crime Junkie.

“A propulsive mystery with excellent writing . . . Simply a great read!”—Gillian Flynn, author of Gone Girl

Nicole “Nic” Monroe is in a rut. At twenty-four, she lives alone in a dinky apartment in her hometown of Mishawaka, Indiana, she’s just gotten a DWI, and she works the same dead-end job she’s been working since high school, a job she only has because her boss is a family friend and feels sorry for her. Everyone has felt sorry for her for the last seven years—since the day her older sister, Kasey, vanished without a trace.

On the night Kasey went missing, her car was found over a hundred miles from home. The driver’s door was open and her purse was untouched in the seat next to it. The only real clue in her disappearance was Jules Connor, another young woman from the same area who disappeared in the same way, two weeks earlier. But with so little for the police to go on, both cases eventually went cold.

Nic wants nothing more than to move on from her sister’s disappearance and the state it’s left her in. But then one day, Jules’s sister, Jenna Connor, walks into Nic’s life and offers her something she hasn’t felt in a long time: hope. What follows is a gripping tale of two sisters who will do anything to find their missing halves, even if it means destroying everything they’ve ever known.

This is a very fast murder mystery/thriller/sister saga. What happens when 2 young women go missing within 2 weeks of each other? Both are ruled cold cases that haunt the surviving sisters of each known victim. After 7 years, Jenna who lost her sister, Jules, reaches out to Nic whose sister Kasey went missing. Jenna believes if they work together, they may be able to discover some new leads. Nic has nothing to lose; she is working a dead-end job since high school, lives in a shabby apartment and recently lost her license due to a DUI. But as they start working together, Jenna pulls back. Why? Are they getting too close to the truth? What will they do to protect the sister they loved and lost?

Nothing is as it seems, and I didn't see the final twist. No real likeable characters, several red herrings, not very believable, especially after 7 years. Ending is very abrupt and left many questions. Quick & entertaining.

This was a great read, and it's a blessing I don't work in any sort of law because I could suspend my belief the entire book. I didn't see the plot twists coming. After reading some others' reviews, this is what I've gathered. Take the law with a grain of salt. Either you're going to love or hate act 3. It's a bold move for the author to do what she did at the end. I didn't hate it, but it was almost too shocking and outrageous to believe.
