Parents need to know that Diary of a Wimpy Kid: Wrecking Ball is the 14th book in the bestselling Wimpy Kid series by Jeff Kinney. Like The Long Haul, most of the book focuses on Greg's interactions with family. This means no bullies bother him at school and he's too busy with chores most of the time for some of his characteristic thoughtless behavior. He's mean a few times to his best friend Rowley, however. And there's a bit of potty humor, including a visual of little brother Manny trying to swipe a credit card on a plumber's partially exposed backside. Violence is mild, with the funeral of a great-aunt; talk of ghosts, zombies, and a scary monster in the drain (with pictures of what Greg imagines). Plus there's a near-fall from the roof and lots of damage to a house. When Greg's at his best, he's creative and resourceful rather than mischievous. Here, he designs an underground house kids will love and puts together a garage sale with his old toys and some rather ingenious marketing.
