The Power of His Touch — Alaina Stanford

You can't kill demons for thousands of years without creating a nemesis or two. But Lilith was different. Rafi's killed demons for millennia, but Lilith was different. She was a sexy kind of fun despite the deadly evil. Rafi looked forward to their encounters. If she wasn't the mother of all demons, they might have been more than enemies on opposite sides of creation. Disguised as an agent of the World Health Organization Rafi searches for the source. When he meets a biochemist named Sophia at the center of the pandemic, everything changes.
