Grandma Must Die — Maureen L. Bonatch

Carman has worn out more towns and last names than impractical shoes protecting the secret of her magic blood. But when a friend goes missing, and another is infected with a deadly spell, Carman must choose. Expose her magic blood by curing the spell -- or stop the infection from spreading by killing the source…the grandmother.

Magic bounty hunter Dylan has scoured libraries of banned magic paraphernalia seeking a method to distinguish genuine witches from impersonators. He suspects unorthodox librarian Carman might hold this information tighter than the hair he's dying to unleash from her bun. With a past as hidden as his sleeve of tattoos, Dylan discovers he's been used to gain Carman's trust and their passion risks more than mixing mortals and magic.
