Miller has taken a painful condition (Juvenile Rheumatoid Athritis) and written a beautiful children's book that not only explains and educates what the condition is all about, makes the reader see what her son has experienced during his life; coping the best he could with this condition.Triumphant!The story is well written as well as entertaining, too. And the information in the back of the book is well researched and thorough. Excellent!
