St Brigid's is a remote island off the west coast of Ireland. It is a barren place and its small community is dwindling. But according to rumour it is a magical place, home to a healing well. Two sisters, Rose and Emer, have resisted the call of the mainland. Rose is beautiful, blessed with love and many children. Emer is unlovely and, worse still, she is cursed by the strange currents that run through her fingers. When a dazzling stranger alights on St Brigid's, she is shunned. She has come in search of a miracle, and the islanders keep their secrets close. But gradually she insinuates her way into the sisters' lives, and even Emer opens her heart. Little do they realise that her quest will endanger the lives of all who remain on the island. Passion will endanger everything they hold dear.
