Maya is a captive. In Grandmother's house in California, she is forbidden from playing or having friends, every word and action is strictly monitored, and even her memories of her mother have been erased - except within the imaginary world she has created.
A world away, in the rugged Wyoming wilderness, a tobiano Paint horse called Artemisia runs free, belonging only to the stars. The mother of a new foal and the lead mare of a harem band in a land where survival is precarious, she embodies the spirit of the wild-and she holds the key to Maya's memories.
En la casa de su abuela a Maya le tienen prohibido jugar o tener amigos; todo lo que hace está supervisado y han borrado todo aquello que le recordaba a su madre. En un mundo muy lejano al de Maya, en Wyoming, una yegua llamada Artemisia cabalga libre bajo las estrellas. Acaba de parir un potro y es la yegua líder de una manada de caballos. Pero Artemisia, además, tiene la llave que puede abrir los recuerdos de Maya.
