Infernal Hearts by Danny Haliwell

“I want to offer you a deal…”

Jason Blackwell thought he had finally escaped his father’s world of magical medicine. All he wants is a normal life as a practicing veterinarian. No supernaturals. No unpredictable magic. Just a small town, regular animals, and walking away from his family secrets…and lies.
Until he’s woken in the night by Levi—an incubus attired in a fancy suit with a Southern drawl, too much charm, and an annoying tendency to always get his way. Jason is his only chance to find his missing brother.
And they have only two weeks to find him…or the demon dies. And finding Levi’s brother might just be the key to figuring out his own father’s disappearance.
Pulled back into the life he thought he had left behind forever, Jason now returns to the shadows and secrets of the supernatural world. Only this time, there’s no hiding from the truth about himself—and his family’s troubled legacy—or from the magnetic demon who pulls at his heart.
But when you make a bargain with an incubus, there is always a price to be paid. The only question is whether Jason and Levi will live long enough to regret it…

Infernal Hearts is a supernatural enemies-to-lovers romance about a magic practitioner and a misbehaving incubus who discover that every deal has a dark side.
