A cowboy with a shadowed past.Untamed Wyoming is nothing like polished, restrictive Chicago--that's why Ellie Marshall likes it. On her uncle's ranch, she's free. Free to practice her calling in medicine. Free to finally connect with her uncle. Free to explore her feelings for mysterious cowboy Rhett Callaway. In this strange place, Rhett is her constant--the one she trusts to help and protect her...especially when sinister machinations on the ranch come to light. But will Rhett's murky past drive him away just when Ellie needs him most?
