The Cydonian Pyramid — Pete Hautman

More than half a millennium in the future, in the shadow of the looming Cydonian Pyramid, a pampered girl named Lah Lia has been raised for one purpose: to be sacrificed through one of the mysterious diskos that hover over the pyramid's top. But just as she is about to be killed, a strange boy appears from the diskos, providing a cover of chaos that allows her to escape and launching her on a time-spinning journey in which her fate is irreversibly linked to his. In this second volume of the Klaatu Diskos trilogy, Tucker Feye and Lah Lia each hurtle through time, relating their stories in alternating viewpoints that converge at crucial moments. Fans of the first adventure will be intrigued by the chance to see the world through Lah Lia's eyes -- no matter how disturbing the vision might be.
