Interesting Historical Fiction for 5th grade

Hi everyone,

In two weeks, I will begin teaching my 5th grade students about the American Revolution. In my small groups, I would like to read a grade appropriate historical fiction chapter book. In my two classes, the Lexile levels range from mid 500's - 1265. 

Can anyone recommend an interesting chapter book for my students. Unfortunately, my county is moving away from using chapter books in the classroom so there are not many options available in my school's book room. 

Thank you!
