When the first boarders arrive, Rosie realizes working at the family stable will be more difficult than she anticipated. The extra horses aren’t the problem however; it’s one of the boarders that Rosie can’t get along with. 

Rosie can’t wait for The Great Adventure—the family’s first summer camp at Sonrise Stable! However the week presents several unanticipated challenges with the possibility of losing old friends—human and equine, becoming a role model to a rambunctious young camper, and facing persecution from an unexpected source. 

With the excitement of summer camps over, Rosie and Carrie work to get their horses in shape for the state 4-H competitive trail ride. The girls are surprised to learn that Abigail, the arrogant new boarder at Sonrise Stable, is also entered in the race. Can Scamper and Zach keep up with her flashy Arabian?

A rascally pony, two run-down carts, and a pile of moldy harness seemed like a strange start to a journey full of ups and downs that led Rosie to the most meaningful Christmas of her life. But looking back, she knew it all began that fall day at the livestock auction. 

Sometimes, real-life events make Scripture sink deeper into our hearts than any sermon or Sunday school class. Rosie couldn’t have imagined that bull riding, a kind Amish family, and a mystery involving five Saddlebred horses would help her come to truly understand the commandment Jesus called the greatest.

In this exciting conclusion to the Sonrise Stable series, Rosie does her best to obey the command Jesus called the second greatest. Love your neighbor as yourself. When she faces a mysterious new adversary, Rosie discovers it's harder to keep that command than she'd imagined.
