Do you like to read? I love that I can make connections with a book, even if the story is something unfamiliar to me.
I used to love reading books, after I had two boys I didn't have time anymore.
Do your boys like to read? There are so many great books out there for kids now!
My oldest loves history books, he is a history buff at 13. 
I enjoy history books too! There are many excellent history books in the Western Canon that have shaped our culture. 
For awhile he was really into World War II, Now he has been reading about the Revolutionary War.
Has he ready any books about George Washington as the leader of the Continental Army during the Revolutionary War? I've been interested in that topic as well.
