The next riveting summer suspense by the author of THE BLOCK PARTY and ONE BIG HAPPY FAMILY, Jamie Day.

WILL THIS BE THE BEST WEEK OF THEIR LIVES... OR THE LAST?

JULIA, DAVID, AND ERIKA grew up together spending summers at their idyllic Vermont lake homes for as long as they can remember. Now adults— with their own sullen teens, endless mortgages, and low-voltage sex lives— the three friends have amassed secrets over the years.

This summer, David is eager to show off his newly renovated home—which now blocks his friends’ cherished lake views—and his much-younger girlfriend. He also, unwittingly, brings a nanny with a hidden agenda. What could possibly go wrong?

When David’s girlfriend mysteriously vanishes after a shouting match, Julia and Erika wonder just how well they know their lifelong friend. The lake harbors a harrowing past: two young women, with no known connection, vanished without a trace thirty years ago. Did the lake take another?

As a search is mounted, an intricate web of lies, deceits, and betrayals spanning generations starts to surface, and everyone finds themselves in danger of becoming the next victim. Of the lake, or something darker.
