After the tragic and mysterious death of his grandfather, Jacob Portman quickly follows a downward spiral and loses himself. Due to the countless stories of the strange orphanage and peculiar children who lived there, Jacob and his father decide to visit the small island off the coast of Wales. The orphanage they found was almost exactly like his grandfather described, except for half of the vacated house being in ruins due to a bomb drop in 1943. However, this didn't deter Jacob, it only intrigued him more. He explored the house and soon entered a time loop: an ever-repeating day used to protect peculiar children blessed with extraordinary gifts. Jacob soon got to know these children and also their ymbryne head mistress, Miss Peregrine. While spending time with them, he soon learned more about his grandfather's past, his grandfathers peculiarity, his own peculiarity, and the invisible monsters that hunt peculiars, hollowghasts. After an increase in hollow attacks, Miss Peregrine and her children are visited by another ymbryne, Miss Avocet, whose children have recently been taken. Soon after, the children themselves are attacked, but are ready and prepared thanks to Jacob, whose peculiarity is the ability to see the monsters. They narrowly escape the monsters at the price of Miss Peregrine being kidnapped by Wights, the evolved form of the Holloghast with the ability to shape-shift into different people and a regained consciousness. Without Miss Peregrine there to continue the time loop, the loop collapses, their house is destroyed, and the children and Jacob are thrown into the following day in 1943, with no way back to the present. What happens next? Find out in the sequel, Hollow City.
