Miss Peregrine: "I'm a type of peculiar called and Ymbryne."
Jake: "Yeah, you turn into a bird."
Miss Peregrine: "Well, I do, yes, but that's not very useful. An Ymbryne's main skill is the manipulation of time. We choose a safe place to stay each day and create a loop."
Jake: "What do you mean?"
Miss Peregrine: "A loop is the last twenty-four hours, rest the loop and the day is yours to live in again. Reset it daily, and you can stay there forever, entirely safe from the outside world. Every Ymbryne commits herself to the creation and the upkeep of a place like this, a home for peculiar children."
