I think this book is ok ,because it tells me what I need to know ,but I don't like nonfiction. I would recommend this book for 3rd- 7th ,because it would probably be hard for 2nd and younger,but easy for 8th and higher. If the book John Tyler by Megan m. Gunderson didn't really help you then this will. John Tyler runs for president,but he was isn't the best. Read the book to find out what happens to Tyler.
