Lena Marsh talks to her reflection. One night, it talks back.
Lena is twelve, and new in town, and lonely in the specific way only a new kid in a new house can be. So when the antique mirror already standing in her bedroom starts answering her back, she doesn't run. She's grateful.
Her name is Elena. She's kind. She's funny. She knows exactly what to say - because she's had all night, every night, to learn.
At first, Elena only helps: the right answer on a quiz, the right joke at the right moment, the right thing to say to a distracted mom. Then Lena starts losing time. A classmate thanks her for a kindness she doesn't remember doing. Her mother laughs a laugh that isn't quite hers.
Somewhere behind the glass, a girl named Callie disappeared thirty-six years ago - and nobody in town remembers her at all.
Lena has until her birthday to prove which one of them is real. But the mirror doesn't take you all at once.
It's kind. It's patient. And it's very, very good at being you.
A quiet, creeping horror novel for readers who like their scares smart, slow, and hard to shake - perfect for fans of Coraline, Small Spaces, and Doll Bones.
