Every day in middle school can feel like the end of the world. Eleanor Dross knows a thing or two about the end of the world, thanks to a survivalist grandfather who stockpiles freeze-dried food and supplies--just in case. So when she reads about a Harvard scientist's prediction that an asteroid will strike Earth in April, Eleanor knows her family will be prepared. Her classmates? They're on their own! Eleanor has just one friend she wants to keep safe: Mack. They've been best friends since kindergarten, even though he's more of a smiley emoji and she's more of an eye-roll emoji. They'll survive the end of the world together
