The Genius Factor: The Genius Factor (Unabridged‪)‬

Every Friday the 13th, sixth grade genius and inventor extraordinaire Nate Bannister does three not-so-smart things to keep life interesting. This time he taught a caterpillar math, mailed a love letter, and supersized his cat, Proton, before turning him invisible.

As Nate and his new (well, only) friend, Delphine, race to stop Proton from crushing everyone and everything in town, they come face-to-face with Sir Jakob Maculte (the 27th Lord of Mayberry Castle and leader of the nefarious Red Death Tea Society).

Known for its criminal activity, killer tactics, and impressive tea brewing skills, the Red Death Tea Society will do anything to get in their way. Nate and Delphine must pull out every mind-blowing gadget, half-perfected invention, and unproven but theoretically sound strategy they've got up their sleeves in order to survive to see Saturday the 14th!
