How do you audit Armageddon? Better get a red pen and some black coffee because it's gonna be a long night.

Cal is a full-fledged accountant now, and after his success on Fidotopia, he's ready for his next audit. Unfortunately, his next challenge is as deadly as it is personal. Cal's brothers and sisters have killed the world of Tittikaka and now the cute kitten people known as the Teeklish are being evacuated and every second counts.

Cal and Audit Team Six are sent into the Withering Apocalypse for the Omega Audit, though this isn't your normal Armageddon…it's so much worse. Holes are opening in reality and demons are leaking out like a punctured yogurt container of evil!

However, in the chaos there is hope. The now dead dungeon guardian–a Maternal Nightmare Mummy named Miriam "Mimi" Drybone–had a secret so powerful that it might change things forever.

Cal and his heroic accountants will have to unravel the secrets of Mimi's Heart Dungeon and take over as dungeon guardians themselves to save the Teeklish!

Too bad Cal's family has issues, so many issues, that they don't really care about cute kitten people in adorable little hats. All they want is power.

It will be up to Cal, Gwen, Helga, and Kronke to stop them.

Strangely enough, it might be Mimi's magical mango cobbler that will save the day!
