On an island off the coast of Georgia, Elle Ranier is losing her memory. Her life presents itself to her in fractured moments: meeting her husband in World War II-era New York, losing her lover, and, through everything, the untouchable Caeruleum jewel blinking through the blue waters of the Atlantic. But there are mysteries her mind is reluctant to reveal. What happened to Gabriel, whose memory both comforts and torments her? Did her husband ever extract the legendary gems from the ocean's depths? Glimmering with incandescent prose, Elle's story is unflinchingly told, disquieting, and lushly lyrical.
