Redwall by Brian Jacques
This was definitely my Boy's "hook book" . . . the book that helped him decide that reading was worth the effort it took. He may have been seven years old when we discovered this series, and it has been a huge part of our family's literary life. There are many books in the series, that don't necessarily need to be read in order, but there are recurring characters that are fun to see popping up in the many different stories. It may be a bit scary for some sensitive six year olds, but for my swashbuckling boy, it was a true hit. The audio books are fabulous. When he was about eight years old, I would have The Boy listen on an iPod with a slowed narrator speed while he followed along in is own book. It helped with speed and comprehension, and the story was compelling enough that he was begging to do it every day!
