Benjamin Bateman’s seemingly ordinary math teacher, Mr. Saunder, turns out to be none other than his terrifying arch-nemesis, Sir Jekku. Even worse, Sir Jekku has teamed up with Mortem, a sinister figure who has tormented the Bateman family for generations. But could there be a third villain in their midst — someone pretending to be Benjamin's friend?

In the fourth thrilling installment of the Benjamin Bateman series, the dark truth finally emerges: why does Mortem delight in hunting down members of the Bateman family? Grandpa holds a grim secret — one that led to Mortem’s very existence. But how can you defeat an arch-nemesis who only grows stronger from fighting, conflict, and chaos?

Could it be that Benjamin’s greatest superpower — his kind heart — is the key to resolving the entire adventure?

Benjamin Bateman and the Wicked Sidekick flips traditional hero stories on their head, proving that the strongest hero isn’t always the toughest, and that enemies aren’t defeated by cruelty or violence.
