The Hey Jack! series' 48-page chapter books fill the need for a cool, real-life boys' series for early readers. Hey Jack! is full of down-to-earth, realistic stories, with word art or illustration on every second page and no more than 50 words per page. Jack's enormous imagination injects the series with fun and humor, and the books are carefully typeset to provide reading breaks. Jack's friend Rebecca is having a birthday party, but Jack's not invited! Does this mean they're not friends anymore?
