After the events of I Didn't Ask To Be The Demon Queen, the kingdom of Wydonia is somewhat stable, and has been for five years now.
Right up until it isn't. Now, with the walls of reality as thin as they are, old gods are stirring, older devils are attacking, and the moon is bleeding. And all before teatime! The same gang that saved the kingdom has to find each other, and this time go a step further and save the world. They might even have to tear a hole in those paper-thin walls between realities, and visit some old friends.
This story can be read stand-alone, but it does follow the events of I Didn't Ask To Be The Demon Queen, as well as its spin-off, We Didn't Ask To Be Here, and for more insight into the characters, those can be read first (or during (or after, I'm not pushy)) if you just want more.
