Paint the Wind by Pam Munoz Ryan

A sheltered girl. A wild horse. An unforgettable journey. This riveting story from Newbery honoree and New York Times bestseller Pam Muñoz Ryan is perfect for fans of Marguerite Henry, Sara Pennypacker, and Rosanne Parry.

Maya lives like a captive.

At Grandmother's house in California, everything is forbidden: friends, fun, even memories. And her life is built on lies―lies Grandmother tells about her dead mother, and lies Maya tells to impress or manipulate. But then she moves to the vast Wyoming wilderness where her mother's family awaits -- kind, rugged people who have no tolerance for lies. They challenge Maya to confront the truth about who she is. And a mysterious mustang called Artemisia waits, too. She holds the key to Maya's freedom. But to find it, Maya will have to risk everything. . . including her life.
