First you can read the traditional story of Jack and the giant, then flip the book and read something completely different (even the illustrators differ)! Here is how the new telling begins:
"I am sure that the rest of you people down below are very nice. But that boy, Jack, is something else. After I was so kind to him, he stole from us, and he hurt my husband. All because we are giants! That's no reason to take our treasures or make my husband fall on his head. See what you think."
I will definitely buy other books by this author, and would encourage you to enjoy this one.
