Every twenty-five years, the isolated, Adirondack village of Pearl Cove hosts a town-wide scavenger hunt called Castle, available only to students in their final year of high school that reside there. The game is simple: decode the clue given to you at the beginning of each round, be the first to find all four of your keys, and win the cash prize. But, as history shows, the game and its owners have a tendency to play their hand in the lives of the participants, leading them unknowingly to places they shouldn't be. Playing Castle then becomes a race against unknown time, rather than a friendly scavenger hunt.
For Pressley, Castle is an opportunity to finally be able to call Pearl Cove home. A win could mean a chance to stay in the village with her girlfriend, who is most skeptical of the game, and properly grieve an unthinkable loss.
For Iris, an avid tree-lover and inside-hater, winning Castle is a chance to finally get out of Pearl Cove, a place in which she never should've landed to begin with. Though she doesn't have much faith in her odds of winning, Iris wants nothing more than to be Somewhere Else. She's willing to take the test of time to get there.
"It took me five seconds to fall. The impact on my chest jarring my body but not my mind. I suppose this is the point where your life is supposed to flash before your eyes as time itself freezes - and it did in a way. But I didn't relive my life physically like walking through an old memory, déjà vu in each step. It was a feeling, something that started in my chest and spread to my fingertips, one so unique to me that it encapsulated each significant event into one single second."
For as long as May can remember one mystery has haunted her world.
A dirty window before her, the grim obstructing her vision, she has lived with a loss she can't identify - that is until one rainy night.
Gradually the spots of dirt May scratched at for so long wipe away with the touch of a finger. But when she looks in will she like what she sees - or will curiosity kill the cat?
