Maya is a captive. In Grandmother's house in California every word and action is strictly monitored. Even memories of her mother have been erased—except within the imaginary world she has created. A world away, in the rugged Wyoming wilderness, a horse called Artemisia runs free. She embodies the spirit of the wild—and she holds the key to Maya's memories. How Maya's and Artemisia's lives intertwine, like a braided rein, is at the heart of this richly drawn adventure about freedom and captivity, about holding on and letting go.
