A frequent character trait used didactically in middle grade novel protagonists is courage. This lesson is an encouragement to engage with the world and new experiences, overcoming obstacles and challenges. The Secret Zoo re-examines this trend, particularly through its protagonist, Noah. Rather than seeing Noah succeed at every turn when he displays bravery, the narrative explores how courage needs to be applied with judgment and conveys that is not an ideal principle in all circumstances. While many of Noah’s actions are brave, they show poor judgment, pride, and bravado, placing himself—and ultimately others—in unnecessary danger.

This theme is introduced early in the novel. Although Noah admits to himself that “[he] can not do this alone” (29), he leaves for the zoo without taking his friends or telling them of his plans. He does not have enough information to make the right decision and unknowingly puts the Secret Zoo at risk. Noah’s actions demonstrate a prideful level of self-reliance; he seriously misjudges his own abilities and the help he needs from others. On the surface, his act is brave and plays into the archetype of the hero quest: Noah departs for the zoo to save Megan from the forces who have kidnapped her.
