Rocío Esquibel is a girl growing up in a Southern New Mexico town with her mother and sister. She defines her neighborhood by its trees—the willow, the apricot and the one they call the marking-off tree. Rocio knows she was born in the closet where she and her sister now take turns looking at the picture of Jesus whose eyes light up in the dark. But at night she enters a magical realm, and in her imaginary Blue Room, she can fly. At first she is a mesmerized observer of the lives of older girls and their boyfriends, but as she finds a job at the local hospital, and discovers a passion for drama and stories, Rocio begins to make her own choices in love and work.
