Simply Love by Catherine Anderson

Even the hardest heart can be softened by love ... Cassandra Zerek is a true innocent in a wild and dangerous place -- but her indomitable spirit and gentle soul make her stronger than anyone suspects.

The owner of a Colorado mining empire, Luke Taggart's wealth and position can buy him anything, yet he has grown bored with a life of saloons, gambling, and loose women. Nothing soothes his restless inner yearning -- until he spies Cassandra, as fresh and pure as a spring morning, and vows he will possess her. The radiant, charmingly naïve young beauty seems blind to the depth of Luke's desire or the lengths he is willing to go to seduce her. But the lady is wise, with an unwavering faith in the magical powers of love. And she's determined to awaken the good man hiding in Luke's tormented heart, for only one precious gift will truly win her: his deep, passionate, and unsullied love.
