A Horse Named Sky by Rosanne Parry

A stand-alone companion to the acclaimed national bestsellers A Wolf Called Wander and A Whale of the Wild.
Exiled from his band, a young, wild horse must find his way across treacherous terrain to reunite with his family after being captured for the Pony Express. A fast-paced animal survival story about wild horses, family bonds, and a changing environment.
Young colt Sky was born with the urge to run. Alongside his band, he moves across the range searching for fresh water and abundant grazing. But humans have begun to encroach on Sky's homelands. With fewer resources to share, Sky knows that he must leave if his family is to survive. He hopes that one day, he'll be strong and brave enough to return and challenge the stallion to lead the herd.
Being a lone wild horse in a vast landscape is not easy, and things get even more dangerous when Sky is captured and forced to run for the Pony Express. Now, against all odds, Sky must find a way to escape and reunite with his family.
A Horse Named Sky is a stand-alone companion novel to Rosanne Parry's New York Times bestsellers A Wolf Called Wander and A Whale of the Wild. Chronicling the perils of westward expansion and the grueling Pony Express from the perspective of a wild horse, A Horse Named Sky is a gripping animal survival story about family, courage, trust, leadership, and loyalty. Impeccably researched, A Horse Named Sky is an excellent book for parents and teachers, and a wonderful choice for fans of DreamWorks's Spirit and Anna Sewell's Black Beauty.
