You'll Be Sorry by Lisa Gardner, Hardcover

A newlywed couple each with their own secrets. An abandoned lodge with a horrific decades-old mystery. And a small mountain town where everyone believes they know their neighbors, in this thriller from a master storyteller.
"Chilling, gripping." —Lisa Jewell, New York Times bestselling author of None of This Is True
For Raquel and Theo Collins, it appeared to be love at first sight. Raquel, a renowned interior designer, and Theo, a brash financial wizard met and married in a matter of months, only to confront a terrible tragedy. Now, unbearably aware of the distance between them, they’ve come to a remote town in New Hampshire to begin anew.
Perched on a ledge with stunning views, the Dixon’s family lodge was once a crown jewel of the mountains. Until late one August night, when both parents and their four children vanished, leaving behind a trail of bloody footprints, and a mystery that has endured for thirty years. Now, its latest occupants, the Collinses, are arriving, and the former grand lodge is once more stirring to life.
