ABE and Pru team up with Mr. Fox and Ratatosk, the insult squirrel, for a new adventure among the gods and lands of Norse mythology as they race to stop the chain of events foretold to lead to Ragnarok--the war that ends the world. It's been a year since friends ABE and Pru joined Mister Fox's Fantasy Investigation Bureau--otherwise known as the Unbelievable FIB--to save their hometown from an invasion of Viking gods and giants. Life has been incredibly ordinary ever since. But that's all about to change when the Norse Allfather, Odin, appears with terrible news: Baldur, his favorite son, has been murdered. It's the first step in a fated chain of events that leads to Ragnarok--the end of the world. Fans of Thor, Rick Riordan's Magnus Chase, and classic Norse myths will cheer as ABE and Pru outrun trolls, explore Asgard and the Viking underworld, and try to outsmart the Queen of the Dead herself to change fate, save the world--and survive seventh grade.
The debut title in a new series featuring unseen realms, Norse mythology, and a pair of most unlikely heroes. "What is the Unbelievable FIB?" That's the question eleven-year-old Prudence Potts discovers on a baffling card no one else in Middleton--except ABE, a new kid with a knack for solving riddles--seems to see. Then a mysterious man asks for ABE and Pru's help investigating mythical beings infiltrating the town, and that's just one of the things Pru finds hard to believe.
Soon Pru and ABE discover another world beneath the surface of their quiet town, where Viking gods lurk just out of sight. They must race to secure the Eye of Odin, source of all knowledge--and the key to stopping a war that could destroy both human and immortal realms. Author Adam Shaughnessy draws from classic lore to create a new world where uncertainty opens the door to magic and the last thing you should do is believe your own eyes. Fans of Rick Riordan and Diana Wynne Jones will delight in the charming characters, abundant puzzles and plot twists, and sly humor of this first novel in a new series.
