Demon Hunter : Birthright (Demon Hunter‪)‬

Jimmy Kaplan has a hard enough time staying on top of his graduate studies in Chemical Engineering and dealing with the death of his quirky, cantankerous grandmother, who raised him from childhood.

When a beautiful, mysterious woman appears in his apartment building and friends start turning up dead, Jimmy finds himself drawn into his grandmother's books on magic and demonology, even as he scorns them as superstition. But all is not as it seems. For his grandmother was tied up with an ancient legacy that Jimmy must face whether he believes in it or not. And he finds that magic and chemical engineering are not so incompatible . . . especially when it comes to beautiful, voluptuous demons.

Contains mature themes.
