The second book in the new middle grade adventure trilogy from the beloved author of The Hero’s Guide to Saving Your Kingdom.

In this thrilling historical adventure, it’s 1883—only a few months after Molly Pepper; her mother, Cassandra; and her friend, Emmett, saved New York from an attack by the megalomaniacal Ambrose Rector while managing to preserve the reputations of Alexander Graham Bell and Thomas Edison, whose technology was manipulated in Rector’s scheme. Their selfless heroism will finally earn them a place in the Inventors’ Guild, alongside the greatest minds of their generation.

Unless, of course, no one knows that they did any of that.

Left with nothing but empty promises and a struggling pickle shop after the government chooses to cover up the crisis, Molly, Cassandra, and Emmett have no idea where to turn—until they learn of a daring Antarctic expedition to the South Pole, where an meteorite of mysterious power is embedded, and where Emmett’s father, explorer and ship captain Wendell Lee, disappeared years ago.

With the fate of the world hanging in the balance, our heroes commandeer an experimental steampunk seacraft to make their play on the pole. But the trip is more treacherous than they realize, and there’s no guarantee that they will return successful—if they even return at all.
