Marissa Locks, newly appointed partner of the Grimm Agency, has a reputation for making a mess of magical matters—although causing Armageddon is a new low, even for her… Marissa is due for a little happily ever after. After all, she did kill the evil Fairy Godmother, end a war, and snag a sweet promotion within the Fairy Godfather's magical-problem-solving Agency. But between maintaining a relationship with someone whose amorous advances can cause third-degree burns, dealing with a killer-poodle infestation, and helping her best friend, Princess Ari, learn to wield spells more powerful than curing a hangover, she’s not getting as much peace and quiet as she hoped. When an enemy from her past appears to exact a terrible revenge, Marissa’s life goes from hectic to hell on earth.

With the end of days extremely nigh, Marissa will have to master royal politics, demonic law, and biblical plagues in a hurry—because even the end of the world can’t keep the Agency from opening for business…
