The Rites of Azathoth
by Frank Cavallo

A notorious serial killer. A forbidden occult mystery. An ancient evil waiting to awaken.

FBI criminal profiler Diana Mancuso thought she had left the horrors of fieldwork behind. Haunted by a tragic mistake that cost innocent lives, she has spent years trying to put the past behind her. But when infamous serial killer Luther Vayne escapes from prison and resumes his reign of terror, Diana is called back for one last case.

A trail of ritualistic murders leads into a shadowy world of forbidden knowledge, secret societies, and occult forces operating behind the scenes of ordinary life. As the investigation unfolds, the boundaries between criminal depravity and supernatural evil begin to collapse.

Welcome to the Rites of Azathoth.
