On the night of her eighteenth birthday, Adelaide Cottlethorne slipped in the tub.

At least that's what they tell her replacement.

Cottlethorn Manor is a house where time stands still. Where memories are never lost. And days are never broken. The family that resides there is perfect. Doll-faced. Porcelain. Well, almost. With anticipations, they await their new daughter dearest. The one to wear the locket. The girl to fill the shoes.

When Olivia arrives at their doorstep, flustered from the eyes in the leaves, with a suitcase in hand, she wants nothing more than a blank slate and a chance to gain a last name. Upon meeting the family that waits behind closed doors, she swiftly takes on the role of the Cottlethorne's perfect new daughter. There's just one rule: "No Mention of the Past".

But when Olivia begins recalling someone else's memories, that are somehow replacing her own, strange melodies, footsteps in the ceiling, and golden visions of blood-filled tubs, she also begins to suspect that nothing at the manor is quite as "perfect" as it seems. The family will not speak a word of Adelaide's death. In fact, no one seems able to recall it happening in the first place. They instead, all seem focused on what they refer to as "the most important day of all". Olivia's eighteenth birthday is coming up soon.

And she is beginning to forget her own name.
