Is Call of the Wild an appropriate teaching novel for grade 12 wherein English is a 2nd/3rd language? Is this novel too simplistic?

Regardless of the
"reading level" The Call of the Wild would provide lots of
challenges for 12th graders-challenges in stretching, learning and discovering. As pohnpei said,
this should not be a major concern with this novel. In all honesty, I completed a Frye
Readability assessment on an Albert Camus novel, and it assessed at a 5th or 6th grade
level.
