Beyond Your Shadows by Marion S. Lee

Some decisions will affect forever. How is it possible to let go of the past?

Having served in the army, Jerry Guyland survives by devoting himself to the young guests in the foster home he has founded on the family farm, together with his uncle. They are his driving force and his joy; the only thing that really matters now.
Max Goodman, the newly arrived riding instructor, will break his monotonous existence. Friendly and outgoing, she will soon make a place for herself among the children and the farm workers.
And although Jerry thinks his heart stayed in the mountains of Afghanistan, the young instructor is ready to prove him wrong. What he could never suspect is that, in reality, Max’s presence has other motives that have very little to do with horses.
When Max’s secret is revealed, Jerry will have to leave his past behind if he wants a future with the woman he loves.
