As a seal shapeshifter, Ara has the once-in-a-lifetime chance to mate. She'll share an island in the Galapagos with a human male, but the rules of the Sisterhood say she must not bond with the man who will father her child.

Nature documentary videographer Nate Adams is astonished when a naked woman shows up on the isolated island. He can't fight his overwhelming attraction to Ara, and she seems eager for his lovemaking, but he knows she's keeping something from him. Will Ara's secret keep them apart, or will she share her mother's fate?
