Jake and Willow return to the fairy-tale realm of Grimmworld to look for their missing father, only to find themselves battling the Big Bad Wolf in a world on the brink of war. 

Willow and Jake have done the impossible and brought the first “happily ever after” to Grimmworld. But in the real world, their father is still missing, and the boundary between universes has grown even more fragile. 

Determined to reunite their fractured family, the twins return to Grimmworld, only to be captured by fairies and forced to make an impossible choice: Steal the Wolf King’s gold claw and return it to the fairy queen in exchange for information about their father, or refuse and become the fairies’ eternal, soulless slaves. 

But to steal the claw, Jake and Willow will have to undergo the Wolf Trials, a perilous series of tests and traps that will push the twins to their limits and beyond. It will take Willow’s strength, Jake’s intellect, and the love and friendship they share—and maybe a few treats from Red Riding Hood’s magical basket—to defeat the Big Bad Wolf, find the next clue to their father’s whereabouts, and perhaps even bring another “happily ever after” to Grimmworld.
