Hollowmere hides a buried heartbeat pulsing beneath ancient soil. Thorne Everhart hears it—echoes between rain and dusk. When a cloaked stranger walks the forbidden north road the silence breaks. Thorne's mother reveals a truth: they guard the Whispering Vault and it has chosen him. Drawn into a surreal realm of flesh and memory Thorne faces his other self—forgotten waiting in shadow. The Vault is waking and something ancient wants to be remembered.
