Grave Danger — Mike Johnston

This hilarious, illustrated middle-grade sequel, combining the humor of Diary of a Wimpy Kid with the action of The Last Kids on Earth, follows a hapless warlock-in-training as he struggles to live up to his great and terrible destiny.

Remember Wick? Son of the Dark Lord, heir to the throne of black and broken glass, and next in line to be the leader of the Grim World? Well, after a major spell gone wrong, he finds himself kicked out of his own castle and shipped off as an exchange student. As if Middle Ages School wasn't hard enough already!
 
Follow Wick through the pages of his journal as he comes up with a genius plan to defeat his foes, achieve greatness . . . and maybe even make a new friend in the process.
