Autumn Sage

This marshal will protect his witness from everything--including his own wounded soul.
 
US Marshal Sebastian Spencer is as coldly determined as the criminals he tracks. He's spent years perfecting his iron control because when he unbends, things break and people bleed. But no one has ever tempted him to unbend as much as the witness in his latest case: a woman he could never think of having.
 
Isabel Moreno wants her life back, though that's impossible when the outlaw who attacked her remains on the loose. She agrees to help with the hunt for the fugitive, even though the marshal is the most unsettling, and intriguing, man she's ever met.
 
When more than just one outlaw threatens Isabel, Sebastian must keep her closer than ever, closer than he's let any woman come--and the most dangerous threat of all might be to their hearts.
