Hello--
A few years back I had a well-known agent for a nonfiction project. The book came close, but didn't sell, and agent wasn't interested in my middle grade novel -- nor were any other agents beyond the nibble point.

I've spent a long time on a new MG novel and back on the query-go-round.
Will post query soon for the expert eyes in these forums.
Am a New Englander implanted in upstate NY these days.
Best,
John
