We need a reading-list for young boys, so they grow up as warped as we did.
I'm sure there are sites with lists of "current" books. But we still listen to Bach and Ellington and Morrison, and there are books which I believe are worthy of a child's attention in 2010-2015. Some have been re-issued; some of the new-series are "updated" into junk. Mostly these books are available pre-enjoyed, in yard-sales or at ABE.com and mostly affordable.
Go, Dog. Go! "
is a classic children's book written by P. D. Eastman" Very 1960s, superficially very "easy", and subtle on multiple levels. Beats heck out of Dick And Jane.
Mike Mulligan and His Steam Shovel, 1939 (ISBN 0-590-75803-9)

Speaking of which:
And to Think That I Saw It on Mulberry Street, also
The Cat In The Hat Comes Back, Dr. Seuss
The Tower Treasure,
Hunting For Hidden Gold, etc from the original The Hardy Boys series; NOT the 1963 re-writes.
The Case of the Roving Rolls A
Brains Benton Mystery by George Wyatt
The pre-1969
Tom Swift Jr have not really gone out of style. Also look for
Rick Brant. Some of the 1950s Brants are just potboilers with old racial attitudes, but the 1960s ones are superb ("The Flying Stingaree"). These can be spiced with the
Jonny Quest cartoons.
Nancy Drew are also mostly good reads.
