From the award-winning author of Steel Beach, Ophiuchi Hotline is set 500 years in the future when humans are bioengineered and cloned, and social and sexual customs have changed.

Humans have settled on moon colonies called the Eight Worlds after being exiled from Earth by the Invaders. But a group calling itself the Free Earth Party is experimenting with weapons in an effort to reclaim their home planet--an effort that could end in the destruction of all humanity.
