Books on Henry VIII
The Terrible Tudors (Horrible Histories)
by Terry Deary (Author), Neil Tonge (Author), Martin C. Brown (Illustrator)

The whole series by Terry Deary is perfect for reluctant readers and those that appreciate the darker side of history. This one covers Henry and his many wives. Kids will find the goofy illustrations, puzzles and quizzes far more engaging than your typical history book.
