Shadow of the Swan (The Novels of Ravenwood)

Lady Constance de Bret was determined to be a nun, until shadows from the past eclipsed her present. Marriage is the safest option, but she insists on a spiritual union, in which physical intimacy is forbidden. Not so easy with a bridegroom who wields unparalleled charm! But a long-buried secret could taint his affection and cloak her in shadow forever. Back from the Crusades, Sir Robert le Donjon craves a home of his own and children to inherit it. From the moment he meets Constance, he feels a mysterious bond between them. When she's threatened, he vows to protect her and agrees to the spiritual marriage, with the hope of one day persuading her to enjoy a "real" one. She captivates him but opens old wounds and challenges everything he thought he believed. Two souls in need of healing. Two hearts destined to beat as one.
