I think this story will appeal to its target audience, but I found it too didactic. Readers need to be able to figure some things out for themselves, and Kehret tells the reader that hunting is bad, poaching is bad, etch. The reader is smarter than that - especially young readers who love animals.
I was mad at Jeremy for putting his family through another supposed death. That is something you just don't do. I would have been better if he had run away. Having experienced the death of a family member, this was just too much for me and a bit too contrived.
