Lucy Clairmont's family treasured the magic of the past, and her childhood fascination with stories of the high seas led her to become a marine archaeologist. But when tragedy strikes, it's Dashel, an American forensic astronomer, and his knowledge of the stars that may help her unearth the truth behind the puzzle she's discovered in her family home. Two hundred years earlier, the seeds of love are sown between a boy and a girl who spend their days playing in a secret sea cave, while the privileged young son of the estate looks on, wishing to join. As the children grow and war leads to unthinkable heartbreak, a story of love, betrayal, sacrifice, and redemption unfolds, held secret by the passage of time. As Lucy and Dash journey to a mysterious old estate on the East Sussex coast, their search leads them to a community of souls and a long-hidden tale that may hold the answers—and the healing—they so desperately seek.
