On a hot summer's day in 1975, young heiresses Willow and Ivy Wilde vanish while playing by a pond on the Stonehold estate, never to be seen again.

Now, fifty years later, Stonehold is again abuzz, this time in preparation for the homecoming of Summer Wilde and Brody Weston, whose upcoming wedding is all anyone in Echo, Washington can talk about.

Nobody knows that Summer doesn't want to marry Brody. That she doesn't want to inherit Stonehold and be tethered to the unshakable darkness that clings to the halls and grounds like cobwebs. Nobody knows because Summer doesn't have a choice—she has to marry Brody, and she's long made peace with her fate.

That is, until she sees Ford Flores—third-generation groundskeeper at Stonehold—for the first time in fifteen years. Ford is everything Brody isn't; she's self-sufficient, quick-witted, effortlessly kind, covered in tattoos, and a woman. And the last time Summer saw her, she'd kissed her—impulsive and electrifying—then she'd ran away like a coward.

Summer Wilde is done being a coward.

But it's hard to take charge of your future in a place like Echo, where the past looms thick as the mountain mist tumbling down the white-tipped Cascades. From ghostly apparitions to secret rooms with mysterious paintings and an old sketchbook with a mind-blowing revelation scribbled inside, Summer begins to realize that if she wants to move forward, she'll have to put Stonehold's past to rest—starting with the unsolved disappearance of Willow and Ivy.

With her wedding only days away, the clock is ticking. Even with Ford's help it won't be easy—no one is telling the truth and everyone has something to hide. Even Summer.
