Appaloosa Summer (Island Trilogy #1)
Tudor Robins

Jared Strickland has been living with loss ever since his father died in a tragic farming accident.
Meg escapes from her grief by changing everything about her life; moving away from home to spend her summer living on an island in the St. Lawrence River, scrubbing toilets and waiting on guests at a B&B.
Once there, she meets Jared; doing his best to keep anything else in his life from changing.
When Jared offers Meg a scruffy appaloosa mare out of a friend’s back field, it’s the beginning of a journey that will change both of them by the end of the summer.
