Good, but maybe not for your 13yo son!
on December 2, 2016
My 13 yo son is a big fan of Munroe's other books, What If? and Thing Explainer, so I got this for him for x.mas. Good thing I looked at it first—
Parents should be warned this book has explicit content (along the lines of "The mathematics of cunnilingus" and stuff like that). I didn't see anywhere where it notes this. Besides that, the book's pretty good :-)
