This is a cute, little story about two friends that are opposites. Despite their differences, they are the best of friends. Prudence is quiet, timid and scared of many things. Moxie is loud and not scared of anything. Moxie is dared and double dogged dared to do just about anything and everything their friends can come up with. She drives a tractor, rides the scariest rides at the fair and rides the high-speed turbo go-cart down High Horse Hill with no hands. When Prudence learns the one thing Moxie is scared of is horses, she can hardly believe it. She loves horses! Just for Prudence (and with Prudence’s help), Moxie overcomes her biggest fear and rides Thunder with Prudence. This book has the neatest, whimsical like  illustrations. I love the borders on the pages and the story this story of friendship is enduring. My only issue with the book is the length. It rambles on and is pretty long for a picture book.
