Good to Know - D.W. Marchwell

Good to Know: Book One
Jerry McKenzie is a reclusive and antisocial artist, quite content to ride his horses and work in his studio, keeping to himself. It's not any kind of life for a child, and when Jerry finds out he's been named his orphaned nephew's guardian, he panics. He doesn't know what to do with a child and isn't sure he can give William the affection and the love the boy so desperately needs.
Then Jerry meets David Loewenberger, the new teacher William becomes immediately attached to, and he starts to see how they could make a family together: a family to replace the one William lost, a family David had given up on ever finding... a family Jerry never knew he wanted.
