Prairie Hearts Series by Radclyffe

In 1860's Montana Territory, Kate Beecher, a young woman from Boston, faces the hardships and hard choices of life on the frontier. Just eighteen and quietly struggling against the social constraints of the era, Kate meets a woman who fires first her imagination, and then her dreams. Jessie Forbes, a fiercely independent rancher, finds in Kate the passion she never knew she had been missing. This is the story of their struggle to love in a land, and time, as cruel as it was beautiful.

Can two outcasts find refuge in one another's hearts? Dr. Vance Phelps lost everything in the War Between the States - her career and her faith in herself. Mae is a frontier madam, used to standing alone. She guards the well-being of the lost young women who come under her care - she just never expected one of them to be a doctor.
