This and Mighty Jack are really a single story in two volumes. So spoilers ahead.
Starting with the way it starts with Lily and Jack in hot pursuit of the ogre that kidnapped Maddie -- up a beanstalk.
Featuring not only goblins, but giants, rats, and more. Like the reappearance of the dragon, a car in a sewer, Lily's sack of plant stuff, pipes, broken ribs, and the effects of goblin blood.
It has an epilogue to hint at future story -- and, oh, yes, confirm a link to Zita.
