In a propulsive thriller by the #1 internationally bestselling author of The Bazt n Trilogy, a female detective follows a psychopathic killer into the eye of a storm.

Amaia Salazar, a young detective from the north of Spain, has joined a group of trainees at the FBI Academy in Virginia. Haunted by her past and having already tracked down a predator on her own, Amaia is no typical rookie. And this is no ordinary student lecture at Quantico. FBI agent Aloisius Dupree is already well acquainted with Amaia's skills, her intuition, and her ability to understand evil. He now needs her help in hunting an elusive serial killer dubbed "the Composer," and in solving another case that's been following him his whole life.

From New Jersey to Oklahoma to Texas, the Composer's victims are entire families annihilated in the chaos of natural disasters, their bodies posed with chilling purpose amid the ruins. Dupree and Amaia follow his trail to New Orleans. The clock is ticking. It's the eve of the worst hurricane in the city's history. But a troubling call from Amaia's aunt back home awakens in Amaia the ghosts from her childhood and sends her down a path as dark as that of the coming storm.
