Farmhand (Bluehills #1)
Lilania Begley

Irina took the job on a whim. She just wanted to work hard enough to forget why her life was on hold and her future uncertain. Daily reminded of a brighter past, a childhood spent on horseback…but her new feelings for Dev were definitely not sisterly. At the end of the summer she’d leave, it was too dangerous to risk staying near him.
As a wildfire threatens the countryside, racing toward the Macquire place, Dev and Irina discover what true partnership can feel like, working together to find the arsonist who is responsible. When the fires die out, are there embers left smoldering in hearts?
