Solved - Motorcycle club romance help

I can't remember any names of characters, the author, or the title.  The H is a big guy in a club who sees a little boy who's alone, sitting beside a convenience store, and sits with the little boy until his mother shows up.  The mother is divorced, the little boy has issues (autism or something like it), and the bio-dad is a huge jerk and is mean to the little boy.  The mom & boy stay with the biker for some reason that I can't remember.

Anyone know this book?
