Abstract: Flight, Alexie's novel released in 2005, focuses on the living crisis faced by the native American juveniles in modern society. The five time travel experience brings the boy back to the starting point and forms a perfect circle, which indicates the end of his healing journey as well as the beginning of his new life. It also implies the transition from the unbalanced to the balanced state, and signifies his retrieval of personal identity. With the application of narrative techniques such as first person perspective, spatial transformation and circular narrative structure, the novel tactfully exhibits the hero's epiphany and his reconstruction of identity, and perfectly combines the content with the form, which enriches the meaning of the novel for one thing, and intensifies its narrativity and readability for another.
