King of the Undies World

Victoria Gousset, rich, beautiful, daft, and heir to an improbably massive fortune, has been kidnapped.
Her father, mercurial underwear magnate Sir Hades Gousset, sees a way to make capital from the kidnap of his daughter and sets his own cunning plan in motion.
Persephone Gousset, volcanic wife of Hades, discovers her husband’s ruse to exploit his daughter's predicament and hatches her own plot to teach her scheming husband a lesson.
The farcical collision of these events propels Victoria on a misadventure that takes her across continents and beyond, while catapulting the Goussets, their friends and enemies into a series of catastrophes that eventually threaten the destruction of the planet.

And all because of some pants.

King of the Undies World is the first volume of the Underpants of Fire trilogy in which Sir Hades, Victoria and Persephone pursue adventures in underwear.

Apparently this is the first in a trilogy, great news if that's true because I thoroughly enjoyed this one and could easily go another two books.
Underpants, millionaires, North Koreans, rats, kidnapping and sticky buns, this book has everything a true comedy book should have.” — Damon Mckinlay, writing on Amazon
