Protected by the Cowboy by Sierra Gamble

Their lives may be in danger, but so are their hearts…

Julia Johnstone has always been known as the risktaker of the family, but when she receives a threatening letter, she’s not about to go after the goon by herself. Nah, she’ll hire herself a bodyguard who’ll also be her detective in crime.
Poor cowboy Adam Blanchard has no idea what he’s signed up for when he agrees to be Julia’s bodyguard, and he certainly didn’t expect to fall for her either.
As their attraction grows, so does the threat to Julia’s life. If the two can’t figure out who is behind the threats, Julia might not be able to celebrate another Christmas ever again.
