“Peter was walking the wall. On the house side, the snow had melted. But on the cemetery side, it still lay on the ground… Holding his arms out at his sides, he pushed off lightly from the tree and wavered for an instant between winter and spring.”
 
While his mom is recovering from a breakdown, Peter travels to live with grandparents he barely knows. Nan and Pa are kind and caring, but Peter senses a strange silence between them, of some past unspoken pain. An old cemetery lies just beyond the stone wall at the end of his grandparent’s backyard, and Peter takes to walking this wall – transforming into a high-wire artist whose exploits he knows well. And so it begins. An extraordinary cast of characters will enter Peter’s life, drawing him into worlds he had never known to exist. Secrets and mysteries swirl like snowflakes above the ancient brick building standing among the headstones – the Winter Vault.
