Computer nerd, Cyra, finds herself crashed and trapped within a cage on a distant planet. When the walls to her jail come down two buff, commando aliens are staring at her. Their camouflage stripes aren't fatigues but the color of their naked skin. Uninterested in her, they leave with the prize they sought, a strange, wild, flying beast enclosed within the larger cage with her. Cyra, knowing she's no longer on Earth, follows the males. Cage is in possession of a great power; he is leader of his Cloud Flyer tribe. His mate is gone, presumed dead. Cage learns that he can no longer reproduce a male heir to keep his all-male tribe safe. The human he encounters, after receiving that devastating blow, is lucky he lets it live. But it's not that lucky for Cyra. Cage has discovered a weapon in her fears. With his new abilities, Cage plans to steal another's mate. War will wage, as a dark new world follows.
