The Wild Wrangler. Heartsgate to Happiness, #1

Amber Wheeler has accepted the fact that her life is destined to be boring. She loves running the bookshop that's been in her family for generations, but it's not always exciting. When she stumbles upon a secret journal, she starts to wonder if being content with her mundane life is a cop-out. Is she just too scared to chase after what she really wants? Rhett Reed knows his unpredictable, and sometimes dangerous, lifestyle isn't good for a woman.
He's sworn not to take a wife until he's done bouncing between bounty hunting, and wrangling mustangs to train and sell. He's never minded the work it takes to break a horse, but when a mysterious woman comes with him on his latest bounty hunt, will he put in the effort it takes to fall in love? Amber meets Dr. Lachele in Heartsgate and learns that romance and adventure both require risks to be taken.
Is giving up everything she knows to travel back in time a price Amber is willing to pay? Rhett believes Amber is out of reach. Can he step away from the edge long enough to picture a future with her?
