As the eve of the great Wizards' Summit approaches, wizards from all over Rockfall Mountain descend on the school at Shadow Tower to refine their craft. When professors start disappearing, it's up to magic-fearing monster sleuths Tank and Fizz to solve this spell-packed mystery and find the missing mages. Aleetha, their detective partner and a wizard-in-training, has dragged Tank and Fizz into the heart of the Shadow Tower, where libraries fly, spells fill the air, and an ancient army of darkness stirs, when she receives a mysterious message from her missing teacher. Using their detective skills, a pinch of magic and a trickle of technology, the friends stumble into a battle that's been brewing for decades. And what starts as a simple missing-persons case turns into a clash of light versus dark magic. Can Tank and Fizz overcome their fears and track down the missing mages before the black magic makes them disappear for good? The Case of the Missing Mage is the third book in the Tank & Fizz series about two crime-solving monsters living under a mountain, following The Case of the Slime Stampede and The Case of the Battling Bots . Stay tuned for book four, coming spring 2018.
