Detective Jonah Hale investigates the supposed death of Naomi Kerr, only to discover that the body buried was a decoy and that she had been manipulating a sound-reactive anomaly hidden in the city. Alongside Lena Voss, he uncovers that the anomaly is conscious, adaptive, and capable of lethal responses to human missteps. Survival depends on listening carefully, understanding patterns, and respecting the spaces that remember. The novel is a tense mystery-thriller exploring perception, sound, and the consequences of interacting with forces beyond human understanding.
