My Name is America has some boy characters. You will need to read a few to see if they mesh with your ideals, though. Some of them, as is true of Dear America, introduce mature themes rather early. The My America series by the same publisher is for younger readers, but the same precaution there.
The Sugar Creek Gang is a Christian series with boy characters.
Other books for boys that I like to recommend are:
The Henry Huggins series by Beverly Cleary
Homer Price by Robert McCloskey
Encyclopedia Brown series by Donald Sobol
Books by William O. Steele (When I worked at a public library, a Mennonite boy liked these, and his parents didn’t object).
If he likes horses, the Black Stallion series
If he likes dogs, books by Jim Kjelgaard (I think that’s the correct spelling; I know it begins with kj, though).
HTH,
Karen
