“Book Descriptions: Detective Frederick Devoe, a half-breed vampire, and his partner have dead bodies piling up. With no similarities between victims except the murder weapon and, with virtually no leads, they're at a loss.
Until the next body turns up.
Their first lead in months takes Frederick to a familiar apothecary where he meets the owner — a kindly witch — who stirs up all sorts of strange new feelings in both his human and beastly halves. While his human half struggles to remain in control, evidence begins to stack up against the little witch, and Frederick does something he'd never thought possible — he finds himself breaking every law that he took an oath to uphold.
Frederick, the only one convinced she isn’t a killer, makes her a promise — that they'd find who was truly behind the murders and prove her innocence.
Will Frederick be able to keep that promise? Or has he damned them both?” DRIVE
