Annabeth Allan, a prim and proper missionary, heads west with her companions to civilize the frontier, but after a wagon‑train attack she must learn the ways of the native peoples with help from rugged Eben McDowell.

Charity Varney is rescued from the brutal, rapacious scoundrel who has illegally bought her, by aristocratic young Christopher Leach, who will take her back to England with him, where he must report to King George III on conditions in the Colonies. BEAUTIFUL, SPIRITED, DESIRABLE Charity adapts quickly once in London, and becomes a darling of the Royal Court. Many men want her and, out of loyalty to Christopher she gives herself freely to those who can help him. But her own hungers are never satisfied--until she meets Sean McDougal, the handsome footloose Irish rogue whose burning kisses--whose very touch--can carry to undreamed heights of ecstasy. TORN BETWEEN LOVE AND DEVOTION Charity's passions are in constant conflict, until she is caught in a maelstrom of degradation and uncontrolled lust that violates her body but can never enslave her soul. IN SAVAGE SPLENDOR Charity fights for the one man who can unchain her passions and probe the depth of her womanhood.
