When I first started reading The Tenth Mistake of Hank Hooperman, I thought, “Oh, no! Not another condescending middle grade fiction book full of bathroom humor!” On the very first page, we find out that eleven year old Hank, who is trying to potty train his little sister, Boo, would prefer his sister called him “Superman”. Instead, her affectionate nickname for her beloved older brother is “Pooperman.” However, Boo’s nickname for Hank turns out to be about the only “potty humor” in the book, and precocious little Boo is a delightful breath of freshness and innocence in a book that otherwise deals with some heavy subjects.

A week ago, Hank’s single mom left him in charge of Boo in an apartment with very little food or money. Hank has taken care of himself and Boo so far with no major errors, but now they are completely out of food and money. And the apartment manager is threatening to evict them. With no family to turn to and no idea where his mom could be, Hank takes Boo across town to the home of a stranger that his mom once mentioned. It may be a level 10 mistake, but what else can he do?

The stranger, Lou Ann Adler, turns out to be an old friend of Hank’s dead grandmother, and she takes them in–for now. But Hank has to find his mom, figure out why she abandoned them, and decide whether or not he can trust her to take of him and Boo in the future. Hank is a good kid, hyper-responsible, and deeply afraid of making a mistake that will ruin their lives. I won’t spoil the story, but there is a positive, hopeful ending, after a lot of trauma, anxiety, and dangerous situations have been resolved.

The Tenth Mistake of Hank Hooperman reminded me a bit of Gary B. Schmidt’s novels Okay for Now and Just Like That. All three of these books show good kids thrown into situations that are way too hard for their maturity levels. And in all three books the kids, the boys, are desperately trying to figure out what to do about their situation and which adults to trust. I’m not sure Choldenko is quite as good as Schmidt at showing the nuances and complexities of the situation, but she’s not bad. Hank Hooperman is a good, believable character, and I really, really sympathized with his plight and his desire to avoid both small and catastrophic mistakes.

Cautions: There’s an ongoing thread about Boo’s potty training, including the words “crap” and “poop”. Hank engages in a major deception, for what seem like good reasons at the time, and he pays the consequences. A female friend at Hank’s new school wants to be his girlfriend, and his male friends tease him about the possibility of kissing her.

I would recommend this one for sixth grade and up. The story portrays positive models of compassionate adult behavior as well as the fact that not all adults are trustworthy. Hank himself is character to root for, even though he does make mistakes and wrong choices.

“Why doesn’t someone invent a way to know if you’re about to make a mistake? A Mistake-a-nator that would light up red if you’re about to mess up. I could use one of those.”
