Maids, Mothers and Crones — Jacqueline Farrell

Professional crone Sophronia Sheridan is still in California, trying to teach her young protégée, Charlie, how to be an effective witch, in between hunting for Billy, the rogue human, who is more than happy to sell other witches to unscrupulous vampires for their blood. Charlie's crone grandmother, Nell, proves to be more of a hindrance than a help, and Sophronia's only real ally is Hagen, the vampire lord. But despite finding herself dangerously attracted to him, she doesn't trust him an inch.
And just when things couldn't seem to get any worse, another vampire appears on the scene, far too interested in Sophronia's past and close to unearthing secrets, that, once revealed, could get her killed…
