His Soul To Keep — M. Flagg

Destiny is rewritten for Michael Malone, a mystically enhanced vampire, with an outcome so unexpected that everyone in his world is stunned -- Michael most of all. Suddenly mortal, he faces challenges unlike any he has ever experienced. Alana, his Guardian and soul mate, questions how the evil that lived within Michael was vanquished. Lukas, his human son, doesn't trust his father's heartbeat, and Michael himself has no answers. The bonds of their love will face the greatest test of all when the ancient demon anchored within Michael for 317 years is discovered alive within an innocent human. Can Michael, Alana, and Lukas destroy the evil unleashed in order to give Michael his soul to keep?
