In this hilarious illustrated middle grade novel in the vein of Diary of a Wimpy Kid and Matt Sprouts and the Curse of the Ten Broken Toes, a boy&’s time-travelling older self gives him an impossible mission: convince his class to be nice to their substitute teacher…or risk the fate of the world.Ethan seems like a normal ten-year-old, but he has a secret. It&’s not that he&’s the one who accidentally filled the sunblock container with glue last summer or that he cracked the screen on his sister&’s phone and blamed it on their baby brother. (Those things may have happened, but they&’ve got nothing on this.) No, Ethan&’s secret is that he knows time travel is real—because his future self keeps coming back to visit him. Lucky Ethan, right? Wrong. Because when Ethan&’s future self shows up, he tends to bring bad news, and he&’s kind of bossy. (Not to mention he&’s always wearing super weird clothes.) This time around, he&’s asking Ethan to do one simple thing: make sure today&’s substitute teacher doesn&’t quit, or else one day she&’ll become an evil dictator who will destroy the planet. But his future self clearly forgot what fourth grade is like, because if there&’s one thing Ethan&’s class is great at (other than losing their homework), it&’s tormenting substitute teachers…
