How does a foul-mouthed angel end up as the last hope for all of Heaven and Earth? When Seraph Emma is maimed and tossed from Heaven by a rogue angel who's taken charge, she fears she'll never be allowed to return. Tasked with the impossible job of showing the self-loathing (and not even human!) Jason his worth, Emma is sure she's doomed to fail. Meanwhile, having wormed his way into Heaven, the corrupt Everett has trapped God in Hell and has designs on unleashing evil everywhere. Fortunately, if there's one thing Emma can't do (in addition to minding her language), it's give up. Determined to save Jason and get back to Heaven-even if it means going to Hell-Emma's plan is simple yet impossible: trick the Devil to save God. What she doesn't count on is the devotion and, well, humanity she finds in Jason; the spirit, hidden compassion, and raw sex appeal within the Devil; and the vulnerability of her own heart. With the help of two unlikely allies, she'll wage the battle for Heaven. But will Emma be sidetracked by a new sort of heaven along the way? What's truly more dangerous? Falling from Heaven, or falling in love?
