I just finished a GREAT book! Big surprise it is historical fiction, I LOVE historical fiction! I started reading this book because I was interested in James Town, and because I never get up to the "adult" section of our library so I read some of the "older" kid books I find downstairs! :) It is a Nutmeg Award Nominee for 2009 in the 4-6th grade category, so I figured it would be a bit too old for Riley, but after finishing it today I think he would really enjoy it! This is a book worthy of our home library by my definition, a family classic because I would read it again! So when there are lots of funds for books this will be one we get!
The author has a website where she has made available a study guide for the book, I would put the study guide closer to the 6th grade level than the 4th, but there are also some great links at the bottom that I think could be useful to many age groups!
So if you are looking for a great adventure, and a great story (and you visit the children's library more than the adult) then I would highly recommend Blood on the River James Town 1607.
