Heartless Souls
Harmonia sacrifices herself to save a friend and is taken by Alexi, Malik, and Talon, her childhood friends now turned Furies, supernatural enforcers of rage, murder, and jealousy. They imprison her and reveal she is destined to complete their power through a mystical bond, but Harmonia refuses to be bound by fate alone. She demands love, not obligation. As her own Fury abilities surface, she escapes and tensions with the three men ignite into desire. A criminal syndicate brands her with a curse that demands her execution, and the Furies must protect her while she rescues her kidnapped mother. During a battle in Hell, Harmonia fully becomes a Fury and defeats the goddess Styx with Medusa's talisman. Nearly killed, she is saved by the Furies' devotion. She binds herself to them by choice, and they build a life together.
Heartless Souls is a standalone spin-off in the Saints Academy series.
