Mirror, Mirror — Phaedra Weldon

Siobhan O'Donnell's quiet life is disrupted when a dead body drained of blood is left inside her Mirror shop. Elf Detective Oberon Geld suspects Siobhan as does the DA -- but only because she's a vampire. Aided by Oberon's estranged brother, Abyssinian, Siobhan is given twenty-four hours to solve the case or face charges of murder.
