Book Four : Will Allen and the Terrible Truth
How can a monster detective save himself and his friends
when his monster-fighting tools lose their magical powers?
Fledgling Monster Detective Will Allen has conquered monsters, overcome bullies, and even survived his mother's cooking, but now he faces a challenge that his cleverness and bravery are powerless against - dealing with GIRLS!
And even if he muddles his way through THAT shiver-inducing horror, can Will rise to the occasion and save himself and his friends from creatures that bring to life their worst nightmares when his special monster-fighting tools, the RevealeR and the MonsterScope, suddenly lose their magical powers?
