The Succubus Within. Demetri Risk

A hidden council. A deadly demon. A temptation that could destroy everything. When a powerful sorcerer is found drained of life inside a warded New York estate, Demetri Risk knows the threat didn't come from outside-it was already among them. As whispers of similar deaths spread along the East Coast, suspicion turns inward, and a chilling truth emerges: a succubus has infiltrated the council itself.
Disguised as a woman of extraordinary beauty, the demon feeds on desire and secrecy, binding herself to the powerful while remaining unseen. Even Demetri is not immune to her pull-and when his wife, Esmeralda, becomes the creature's next target, the danger turns personal. With time running out and trust unraveling, Demetri must expose the demon before another soul is lost. But defeating a succubus requires more than strength.
It demands discipline, sacrifice, and the courage to confront the darkness within. The Succubus Within is a supernatural thriller blending urban fantasy, occult mystery, and moral suspense-a standalone case in the Demetri Risk series.
