The Year of My Miraculous Reappearance

In the book, Bill one of the main characters, has down syndrome. Although his sister cares for him, he still doesn't receive the right kind of caring. He doesn't have a reliable person to count on since his sister and mother aren't good influences as well as care givers. His mother can't provide for her family and has to rely on men for their help. I would recommend this book as it is entertaining and somewhat informational.
