Now that she was free, Mary would never again allow another man into her life. Her battered heart was closed to friend and lover alike—but it was not closed to revenge. As eager as she was to bring down her enemy, however, she could not do it alone. She had to accept help—help which might be more dangerous than anything her foe might contrive. For the outstretched hand belonged to a man she had betrayed—her once fiancé, Lord Summerton, and she feared that deep in her heart lay the long-buried embers of the love they once shared. Lord Summerton knew he was a fool to even think of tangling with Mary. She was trouble with a vengeance and he already had enough complexity in his life. He was sure their love had been but a young man’s fancy. Still, to see her so wounded and not offer his aid was beyond him—even knowing that a second betrayal would damage him past mending.
