My youngest got The Hobbit (the graphic novel) for Christmas and she's reading it.
Tonight, she painted a hobbit door on a small canvas.
Note: She also got several of these small canvases for Christmas.
I often give my daughters illustrated or easier versions of novels, Shakespeare's plays, Greek myths, etc. before they are assigned the actual plays, myths, or books for school.
I often read these kids' versions, too, before reading the grown-up plays or myths!
In my experience, an easier, illustrated version allows people to grow familiar with the characters and plots, fall in love with the stories, and talk to their older siblings about them.
Sometimes immediately, but always eventually, my girls also read the actual books.
