My 8yr old son was not a big reading fan. The 30mins. a day that he needed for school was torture for all of us. I bought this book on a recommendation from a friend. I'm glad I did. He loves these books. He reads all the time. He rarely stops at 30 min now, but continues on for 45mins to 1hr. They are easy for him to understand and do his mini reports on. And they are challenging enough to help him improve his reading level.
