"On prom night, Caroline Winterfield walked away from the ruins of an abandoned mansion called Haven Cliff and into the woods...never to be seen again. Only her three best friends know what really happened. But a secret is a secret, and a promise is a promise--even when it shatters lifelong friendships. On the twenty-fifth anniversary of that night, Midge, Kelly, and Talia reunite at Haven Cliff, now a gleaming architectural jewel. But they aren't alone. Someone is watching. Someone who knows what really happened to Caroline--and to the man who now lies dead a stone's throw from where she was last seen. Police detective Midge knows she's dealing with a murder the moment she sees the item clutched in his lifeless hand. Only three other people in the world would grasp its significance. That means Kelly and Talia are either involved or in danger, because Caroline is long gone...or is she?"--
