Desperate times call for desperate measures, and the substitute teacher just begs to be made desperate for it.

There's no denying it. Innocent, quiet Clive isn't just fully aware of the powerful capabilities and transformative properties of the little purple pills stolen from his father's lab, his body aches for them. Despite those recurring, very adult dreams and fantasies he's still too inexperienced to understand and the way his own body betrays him and the most unexpected moments and situations, Clive is determined to never use one of the powdery tablets again.

But he does have one stashed away in his backpack - just in case. School can be full of surprises, and Clive's little life, as it turns out, is guaranteed to be.

This day seems to be just another school day, just another math class: easy, uneventful. Until she shows up: the substitute teacher from hell.

Miss Adlersflugel is one terrifying temporary teacher, and it's apparent from the very first moment she steps into the classroom that no student will be left unaffected. In fact, they may not even be allowed to leave class at all.

Clive doesn't want to be a hero; he definitely doesn't want to draw attention. But someone has to save the day and rescue the class from prolonged torture, and Clive is the only one armed with a secret solution.

It's too easy to slip one over on the unsuspecting substitute. What happens after isn't so easy to deal with. But Clive's growing up fast, and, as it turns out, the substitute is actually an excellent teacher.
