Book description:
How far would you go to rescue your child? A mother races against the clock—and finds herself on the wrong side of the law—in a desperate fight to save her teenage daughter in this pulse-pounding thriller from the author of Reese’s Book Club Pick and New York Times bestseller Wrong Place Wrong Time.
There is nothing that Simone won’t do for her daughter, Lucy. The two have always been close, and with Lucy about to leave home for university, they depart the UK for a vacation to Texas to spend some quality time together. But when Simone awakens on their first morning in the desert, Lucy is gone, missing from their rental cabin. In her place is a cell phone, and a voice on the other line issues a shocking ransom demand. Don’t tell the police. Come to this location. And be prepared to do a deal…
Though Simone’s husband urges her to bring in the authorities for help, she knows she can’t take any chances. The kidnappers might kill Lucy if she tells anyone. No mother would take that risk. Instead, that night, she drives to the isolated meet-up.
What she finds there changes everything. The mysterious kidnapper doesn’t want money. They want Simone to do something. The unthinkable.
A catastrophic chain of events is set in motion, with chilling consequences that extend beyond Simone and her family. What follows is a heart-pounding journey through the small towns and punishing deserts of remote Texas, in which Simone’s courage—and morality—is pushed to the brink as she discovers what it truly means to be a mother.

Gone Girl by Gillian Flynn
On a warm summer morning in North Carthage, Missouri, it is Nick and Amy Dunne’s fifth wedding anniversary. Presents are being wrapped and reservations are being made when Nick’s clever and beautiful wife disappears. Husband-of-the-Year Nick isn’t doing himself any favors with cringe-worthy daydreams about the slope and shape of his wife’s head, but passages from Amy’s diary reveal the alpha-girl perfectionist could have put anyone dangerously on edge. Under mounting pressure from the police and the media—as well as Amy’s fiercely doting parents—the town golden boy parades an endless series of lies, deceits, and inappropriate behavior. Nick is oddly evasive, and he’s definitely bitter—but is he really a killer?
