Beyond the Starry Sky — Celine Chatillon

To avoid being drafted by Agent Elliot Johnson into a mysterious government agency, lovers Penny and Wolf use the silver coffin to return to Eden and shapeshift into wolves. They hole up in a cave where Penny experiences an out-of-body lovemaking session with Elliot -- who turns out not to be such a bad guy after all. He has a thing for Wolf as well.

The three enjoy their group sexual encounters and shapeshifting in the beautiful primordial world, but something familiar about the dying red star above makes them believe there's more to Eden than meets the eye. Will their unseen hosts make their presence known at last?
