The distant world Artemis is a pleasure planet created out of bare rock by a technologically advanced human empire that provided its richest citizens with a veritable Eden to play in. All tech was concealed and the animals (and the humans brought to live there) were bioengineered to help the guests enjoy their stay…but there was always the possibility of danger so that visitors could brag that they had "bested" the environment.

Stranded archaeologist Griffin is determined to make his way back to his home world with news of the Artemis discovery. He and his gene-modified native companion, the huntress Adara, and her psyche-linked puma Sand Shadow, set out to find another repository of the ancient technology in the hope that somehow Griffin will be able to contact his orbiting ship.
