Zombie, Or Not to Be — Kyle Sullivan

Something is rotten in the state of Deadmark, but of course there is: it's filled with zombies.
This brainy and hilarious middle-grade parody of Shakespeare's Hamlet follows a young science-minded zombie named Edda as she deals with a myriad of death-altering problems including a climate crisis caused by the anti-science humans in Ignorway, the disappearance of her mom, and the greedy scheming of her villainous Aunt Agonista.
