I checked out this book because it was the only book on Calvin Coolidge in my library (they had placed it in the adult section.) The vocabulary is adult while the writing style is for children.I wish I hadn't checked it out. The book focuses on Coolidge the human being and episodes such as how hurt he was by the death of his son. I wanted information on policy choices. Lastly, there is nothing about Mexico in the entire book. Maybe we had improved relations with them, I don't know. But I do know that "This was a time of Ku Klux Klan resurgence..." and that's all we get about it!If you give this book to any child, be they ages 9-12 or grades 6-9, you deserve to be slapped.
