A locked-room Christmas mystery where riddles reveal deadly family secrets... and the only escape is through the truth.

Fans of Agatha Christie and Lucy Foley will savor its locked-room twists, interactive puzzles, and chilling emotional stakes. Play along, uncover the truth, and beware: at Endgame House, the most dangerous gift is buried in the past.

Lily Armitage never wanted to return to Endgame House. The grand estate holds too many painful memories--including the unsolved murder of her mother, twenty-one Christmases ago.

But when a cryptic invitation arrives, Lily can't ignore it. Her aunt has resurrected the family's infamous holiday tradition: twelve days of riddles, one each day until Twelfth Night. The prize? The keys to Endgame House--and a promise to reveal her mother's killer.

Snowed in with her estranged, scheming cousins and a deadly game underway, Lily must confront the ghosts of her past, decipher riddles that cut to the bone, and survive a chilling race for the truth.

Because at Endgame House, everyone has something to hide. And this Christmas, the truth is worth killing for.
