Harry Potter mania having subsided (insofar as that’s possible), we’re heading out of Hogwarts and all the way to South Africa for our next boarding-school adventures. Here we find 13-year-old John “Spud” Milton, nicknamed by his dorm mates after they see his you-know-what in the shower. A best-seller in its native country and fun for older kids and adults alike, this YA novel details farting challenges, illicit night swims, drunken parents—the stuff of adolescent dreams.
