In the snowbound town of Greyford, Vermont, math teacher Ethan Cole has spent five years living quietly after the death of his wife, Anna.
Then Mia Harper, his most brilliant student, disappears.
Before vanishing, Mia leaves behind a strange sequence of numbers in her notebook. The police think she may have run away. Ethan sees something else: coordinates, a hidden cabin, and a clue pointing back to Anna’s death.
But Mia’s disappearance is not what it first appears to be. Part of it was staged. Part of it became real. And the deeper Ethan follows the numbers, the closer he gets to a secret buried inside Greyford’s most powerful families.
Anna’s death was not an accident.
Mia’s birth was not what the records say.
And the man leading the investigation may be the one who has the most to lose.
Some truths are not solved.
They are survived.
