Aos Si

When Carla's mother drags her from their home in Denver to the-middle-of-nowhere Colorado, Carla figures her life is over. But a mysterious neighbor embroils her in a battle between the ancient and powerful Aos Si.

Then she meets Shade, a servant of the evil Aos Si. Carla's attraction to Shade is as deep as the power flows that surround them, but her attempt to free him from evil sinks them both in deeper and escalates the war.

Grab your flashlight and dive under the covers, because Aos Si will keep you turning pages well past your bedtime.
