Chinese Myth in "Daughter of the Moon Goddess"

The Busy Girls Book Club loves a good retelling/reimagining of a classic myth. Daughter of the Moon Goddess is based in a Chinese myth about the woman on the moon, but the novel gives it a big spin. It's an epic adventure tale, but very wholesome. But is it worth 500 pages?
