Describe Celie and the mature woman she becomes at the end of the novel?

Celie is the heroine of the novel. Most of the letters that comprise the book are letters Celie writes to God or, after learning that her sister Nettie is in Africa, to Nettie. Celie does not know about Nettie's attempts to communicate with her until Shug finds the letters from Nettie that Albert has hidden. Through the character of Celie, the author is able to present her message of sexual liberation and self-determination for women. Through Celie's voice, which speaks in black folk English, life in the world of a poor, black, rural sharecropper family unfolds. In the beginning of the story, Celie is a young girl who has been raped by her stepfather, who later sells her to Albert, her husband. Both men treat Celie cruelly and without any regard for her needs or feelings. Celie is forbearing and a hard worker, for which every one praises her. When Albert's mistress, Shug, comes to live with them, Celie becomes liberated from her oppression because of Shug' s intervention on her behalf, and because she learns to stand up for herself with Shug's encouragement.
