Limerick, Ireland. The O’Brien family’s driveway. American Oscar Harvey opens the trunk of his hosts’ car and finds the body of a woman, beaten and bloody. But let’s start at the beginning.

Kate and Mannix O’Brien live by Curragower Falls in Limerick, in a lovely house they can barely afford. Kate decides that her family needs a vacation, and is convinced her luck’s about to change when she spots a gorgeous Manhattan apartment on a home-exchange website. Hazel and Oscar Harvey and their two children live on Manhattan’s Upper West Side. Though they seem successful and happy, they too need a change of pace, and the house swap offers a perfect chance to soothe two troubled marriages. But this will be anything but a perfect vacation. And the body in the trunk is just the beginning…

A riveting page-turner for fans of Paula Hawkins.
