I read these to my five-year-old son as his first "chapter books", with a little self-editing along the way. They are good - very imaginative, the writing has great imagery and decent character development. My son was not scared by the images (but some could be) but rather it ignited his imagination. Some language might be unpopular with some parents (name calling and the such). Very quick read for an adult, an easy read if you read to your child (very short chapters) and good enough writing to keep the parent entertained as well. Best part was that he was chomping at the bit to read each night, and begged for "just one more" chapter each time!
