The Misshapes: The Coming Storm introduced us to Sarah Robertson, the young girl whose less-than-super powers relegated her to a group of misfit heroes known as 'Misshapes'. Now, after an exciting summer fighting storms, Sarah Robertson returns home a different girl. But Doolittle Falls is in chaos: the newest Freedom Man documentary is shooting and Sarah's Hero role model, the Black Zephyr, is in town, recreating scenes at giant scale.
And with the election of a new President, Geoff Bergeron, things take a dark turn. Heroes are given extraordinary freedom, and the results are less than super. And certain people in the administration have a vendetta against Sarah's mom, aka the supervillain Mrs. Annihilation, and the entire Robertson family. And after a party goes terribly wrong, Sarah finds herself the pawn in a very dangerous game.
Sarah takes the investigation into her own hands, looking into the into the true origins of her mother's turn from hero to villain. Soon Sarah discovers a devastating secret that could topple the nation, and if Sarah and the rest of the Misshapes don't stop this looming threat, the world as they know it faces Annihilation.
