Violet and Felicity have been at Miss Peregrine's loop for almost 100 years and counting. They've been through everything together, including helping each other through each other's peculiarity. Violet can copy, or in extreme cases take away, other peculiarities and shape shift while Felicity can transform into a feline humanoid. Throughout their time at the loop, they acquire the affections of Enoch O'Connor and Finnick Valentine and create a life together. What will happen to the sisters when their loop opens up to a fellow Peculiar named Jacob?
