Every Friday the 13th, 6th-grade genius Nate Bannister does three not-so-smart things to keep life interesting.

This time, he taught a caterpillar to read, mailed a love letter, and super-sized his cat Proton before turning him invisible.

Now Proton is on the loose, and Nate and his new friend Delphine must reverse the experiment before the cat crushes everything and everybody in town.As if that's not enough, the Red Death Tea Society, known for its criminal activity, killer tactics, and tea-brewing skills, is plotting against Nate and Delphine.

The dynamic duo must use their creativity, courage and friendship to save the day.

Paul Tobin blends wacky humour and chaotic high jinks in this rip-roaring, action-packed middle-grade debut;perfect for fans of David Walliams and Tom Gates.
