Having grown in a sleepy, backwater, Florida town, the most interesting thing in Jacob Portman's life was his beloved grandfather Abraham; a natural storyteller who can tell you all kinds of fantastic stories about his childhood.
When Abraham is violently killed, Jacob is left with his grandfather's unique collection of photographs and his stories, that he could never forget.
As Jacob's sadness draws him to a remote Welsh island, he is met with a growing mystery surrounding the ruins of Miss Peregrine's Home for Peculiar Children, where Abraham grew up.
Jacob notices that everything, even time itself, is slipping out of place as he traverses the crumbling corridors and dusty rooms.
Jacob discovers that the unusual and amazing children who were raised with his grandfather, all have extraordinary powers and reside in a series of time loops, meaning that none of them are the age they appear to be.
