The last thing Jacob Portman saw before the world went dark was a terrible, familiar face.

Suddenly, he and Noor are back in the place where everything began - his grandfather's house. Jacob doesn't know how they escaped from V's loop to find themselves in Florida. But he does know one thing for certain: Caul has returned.

After a narrow getaway from a blood-thirsty hollow, Jacob and Noor reunite with Miss Peregrine and the peculiar children in Devil's Acre. The Acre is being plagued by desolations - weather fronts of ash and blood and bone - a terrible portent of Caul's amassing army.

Risen from the Library of Souls and more powerful than ever, Caul and his apocalyptic agenda seem unstoppable. Only one hope remains - deliver Noor to the meeting place of the seven prophesied ones. If they can decipher its secret location.
