Succubus Shadows by Richelle Mead

A sharp-witted succubus working in a Seattle bookstore must juggle messy romantic entanglements with escalating supernatural threats as political battles among demons and otherworldly forces spill into her life; pressed to choose between love and duty, she confronts dangerous enemies, reveals hidden loyalties, and grapples with what it means to protect people she cares about while facing the consequences of her own nature.
