Book 1

Mighty Jack

by Ben Hatke

Published 6 September 2016
Jack might be the only kid in the world who's dreading summer. But he's got a good reason: Summer is when his single mum takes a second job and leaves him at home to watch his autistic kid sister, Maddy. It's a lot of responsibility, and it's boring, too, because Maddy doesn't talk. Ever. But then, one day, she does talk. Maddy tells Jack in no uncertain terms to trade their mum's car for a box of magic beans. It's the best mistake Jack has ever made. The little garden behind his house is about to become home to tiny onion babies running amok, dangerous biting cabbages, and, in a fiery cliff hanger at the end of this first volume: a dragon.

Mighty Jack and the Goblin King

by Ben Hatke

Published 5 September 2017
The garden behind Jack's house has gone wild with creatures set loose by the magic beans Jack and his kid sister Maddy planted. One particularly mean creature has kidnapped Maddy and carried her off. Now Jack and his neighbor Lilly must follow her to a world between worlds beyond the vines and stalks, where giants grind the bones of human children to feed their beast in the castle up above, and a fearsome goblin king rules down below. It'll take more than Lilly's bag of concoctions and tricks, and more than one hero, to rescue Maddy, reunite Jack's family, and bring them all safely home again.

Jack and Lilly are no strangers to heroics. They've befriended dragons, battled giants, and even earned the loyalty of a goblin army. So when they meet Zita the Spacegirl, fresh from her interplanetary travels and seeking their help to face a new threat, they're more than ready for another adventure.

But the danger growing just outside the door to their world is greater than anything the new friends could have imagined. An army of giants and screeds stands ready to lay siege to Earth, determined to put the age of humans to an end.

With the gate between worlds growing weaker and time running out, can the heroes come together to save their world from their greatest enemy yet?
