Elena Carter has loved the sea all her life. As an underwater archaeologist, she works with it every day, cajoling it into giving up the treasures and mysteries of its past. But when she pulls a handsome stranger from the water in the midst of a storm, she realizes there is much she still has to learn. Taking shelter from the tempest, they experience sensual awakenings, pleasures different from any they have felt before. But the stranger, her intoxicating Prince Orion, disappears, leaving nothing but an ancient artifact. Reluctantly returning to her landbound life, Elena finds more pieces to a puzzle that baffles her even as it hints at greater discoveries yet to be made. She longs to feel Orion's arms around her just one more time, and to ask him about the secrets hidden in the deep, secrets inextricably bound up with Orion and their unquenchable passion. But who--or what--is he? And once she has known the touch of the sea, can Elena return to the world she left behind?
