Every Which Way But Dead (Rachel Morgan 3)

Plot

To get demon Algaliarept to testify at the trial of evil vampire Piscary, who poses an imminent threat to witch Rachel, she agrees to let Algaliarept become her familiar and share her aura. Rachel is certain she can maintain control, since she is keeping her soul. When she changes places with the demon's old familiar, Ceri, she takes pity on the girl and rescues her from the demon's clutches. Rachel is distracted by the two men in her life. Boyfriend Nick is pulling away after Rachel accidentally made him her familiar. Unsure of how to reconnect with him, Rachel finds she isn't immune to the charms of Kisten, a sexy vampire who worked for Piscary. As she finds herself falling for Kisten, she learns that Algaliarept poses a greater danger than she first expected.
