What is the theme in Love Medicine by Louise Erdrich?

In addition to their ties to family, the characters in Love Medicine hold their cultural heritage close to their hearts. They try to live in contemporary society while keeping their Chippewa traditions alive. Lipsha Morrissey presents a good example. The family recognizes that Lipsha has the "touch," that he possesses the ability to heal with his hands as many of his ancestors could. He tries to use his ability to make his grandfather love his grandmother again. Feeling at loose ends when he cheats on his potion for love medicine and his grandfather dies, and having the newfound knowledge that Gerry Nanapush is his father, Lipsha allows the white man's world to lure him into joining the Army.
