Love is a Gift (Heartland #15)

the long version

When Amy journeys to Australia with her sister Lou to visit their father on his horse ranch, she has difficulty feeling a part of his new family. Lou gets along easily with his wife and three-year-old daughter, Lily, but Amy can't look past the fact that she was just three when her father left. So Amy delves into the stable work. But when she reaches a breakthrough with one of the jumpers, the other trainers resent her success. Amy laments that she can't do anything right away from Heartland. It takes a family crisis for Amy to discover she can claim new roles -- and make new friends.
