Alex Carlisle owes a debt beyond cash. Once upon a time—all of three months ago—Alex found himself in a foreign land hunted by mercenaries and demon lords. Only the intervention of a sultry, playful jinn got him home again. Zafirah didn't help him for free. Now she's come to collect. With her sights set on a dangerous family of ancient sorcerers, Zafirah needs every edge. She needs not only Alex, but the friends and lovers he brings with him. Her quest threatens to extract a price from angel, demon, and mortal alike... and most especially the witch who brought them all together.
