Quest For Love (Songs of the Mages #4)
Jean Hart Stewart

Jason Townsend determines he must sever his ties with his twin Jono and find his own path in life. His mage's inner voice demands he go to Ireland, and there he meets Aislinn, a Quaker contemptuous of his First World War heroism and his reputation as a ladies' man. She thinks he's the antithesis of any man she could ever want. Now he must not only find his essential self, but is determined to convince Aislinn he's not the detestable Lothario she thinks him.
His quest becomes complicated when a villain is determined to destroy Aislinn and the young boy she's protecting. Jason must assert his powers as a mage to save her and prove his love.
