Here to Stay - kindle e-book by Kristine Raymond

Not your typical Western!  Set in 1867 Arizona Territory, Here to Stay is a gritty, real to life romance that goes beyond the typical boy-meets-girl story.
Kate Ryan is starting her life over after a series of horrific events.  She is determined to persevere and she is just as certain that she will always be alone.  She knows that any man who finds out about her past will leave her.  But that doesn't stop her from falling for handsome Sam Mackenzie, the cowboy who answers her advertisement for help on her ranch.  Though she tries to keep her distance, she finds that she is inexplicably drawn to him.
Sam is immediately attracted to Kate and he knows that beneath her cool exterior lies a woman of passion.  He does his best to integrate himself into her life and quickly falls in love with her.  Upon learning her secret, he is amazed at her resilience and sets out to prove to her that she is worthy of love.  Just when it seems that their future is secure, Kate's past catches up with her and she makes a decision that threatens to end her chance for a happily ever after with Sam.  Feeling hurt and betrayed, Sam must decide whether or not to risk his heart for another chance with Kate.
