But Benjamin’s latest mystery has nothing to do with feline assassins. With the aid of his bodyguard-slash-cook Clayton and special computational agent Dr. Fang Mei, Benjamin pursues a cult with nefarious plans of a mathemagical nature. The Red Lands Cult has gotten their hands on a Methuselah Equation, and anything with his name on it ultimately equals no good.

If Benjamin doesn’t unravel their plans in time, they will bring to life an ancient enemy with the power to destroy the world. In order to bring the evildoers to justice, equations must be solved, villains dueled, and questionable meals consumed.

Never fear! Benjamin Hu is on the case.
