The latest entry into this category is Wild Things: The Art of Nurturing Boys, by Stephen James and David Thomas. I haven't gotten to read the whole book yet, but I know this is a keeper. Check this line, from the intro:
"Whenever boys are in the equation, you may have to broaden your definition of normal."
I encourage you to check it out -- and to swing by Weird, Unsocialized Homeschoolers on March 10 for an interview with the authors.
