Once Upon a Legend by Delilah Devlin

When budding dime novelist Prudence Vogel travels west to meet legendary gunslinger Jake White Eagle, she discovers he really is the tall, handsome hero of her novel. Flustered and out of her element, Prudence is determined to shadow the handsome sheriff to lend authenticity to her story.
While Jake certainly finds Prudence attractive, her constant presence is distracting. When things she has written seem to be coming true, he decides to get closer to see whether she’s part of a criminal enterprise he’s been trying to uncover.
