They made a vow. They kept their promise. But someone else is desperate to break it. Betrayal and revenge collide in this pulse-pounding domestic thriller for fans of Listen For the Lie, The Guest List, and The House Across the Lake.Morena Taylor and Wren Murray should have been best friends; their families owned the only cottages on a remote lake. Though Wren's family didn't expect-or want-company from the party-animal Taylors, they summered together every year. Until one of the children vanished. The Murrays say it was murder-they're sure the Taylors are responsible. The Taylors claim they're innocent. But no one can prove a thing. A decade passes with no arrests, no justice for the grief-stricken Murrays, nor resolution for the Taylors, whose lives were ruined by the fallout.So when a cryptic invitation promises answers, Wren and Morena's desire for closure overrides their reservations. Though they have no idea where they're going, they get into the Town Cars sent for them, assuming they'll soon hear a confession. They never expected the drivers to take them back to the isolated lake. They certainly didn't expect to see each other there, never mind their families. Accusations fly; old wounds tear open. Wren and Morena would rather kill each other than speak. But the feud between their families becomes the least of Wren and Morena's problems when one guest is horrifically murdered mere feet from the rest. And they can't call for help; the landlines have been cut. There are no boats, no cars-no escape. This isn't a confession-never was. Someone is settling scores and revealing unforgivable secrets, each more damning than the last. No one is innocent. They have no idea whom to trust. And every brutal revelation brings them closer to becoming the next victims. Morena and Wren never expected to be allies. But their survival depends on it.
