Keeping secrets is a dangerous game. No one knows that better than Lily Matthews.



Desperate to escape an obsessive ex-boyfriend and a dark past that continues to haunt her, Lily agrees to a girls’ trip at a secluded lake house deep in the Adirondack Mountains. It seems like the perfect place to disappear for the weekend.



Until a storm rolls in and a woman shows up at their door in the middle of the night with a chilling accusation: years ago, a girl went missing from a nearby boarding school, and someone inside the house is responsible.



She’s been watching them.



She knows everything.



And now she wants to make them pay.



That’s the thing about secrets. The darkest ones always come to light.



Told across a propulsive dual timeline between the present-day lake house and an elite Adirondack boarding school fifteen years earlier, Your Deepest Darkest Secret is a suffocating psychological thriller packed with twists you won’t see coming, dangerous friendships, buried trauma, and a pulse-pounding finale.



YOUR DEEPEST, DARKEST SECRET is perfect for fans of The Housemaid, The Only One Left, and In a Dark, Dark Wood.
