In a Heartbeat (Rosewood River #5) by Laura Pavlov

Wren Waterstone isn't just one of the most decorated equestrians in the world--she was also my best friend for as long as I can remember. Until she wasn't.

Now she's back in Rosewood River, and thanks to a temp agency, Wren has been placed at my ranch. I have no intention of allowing my ex-best-friend to work for me, but when I see the desperation in her eyes, I can't turn her away, even though I know I should.

Old habits die hard.

Seeing her every day is more challenging than I expected. She's guarded. Wounded. And she looks at me like I'm the enemy. I need to know why. The more time we spend together, the more the lines between past and present blur--and we find our way back to one another. The only problem is, she's got big dreams to chase.

And I only want to chase her.

I've loved this girl my entire life, and our time apart didn't change that. I let Wren Waterstone get away once. Am I really going to make that mistake again?
