Seven different girls, by seven different writers, all discover similar, haunting skeleton keys in places that seemed to be hidden. Once discovered, every girl suspiciously moves from different countries all around the world; all to the same place where their mothers had lived; Ithaca, New York. Soon after enrolled in the same high school, the girls somehow find their ways to each other for a reason that is explained quickly after- each of them have keys, and each of them are starting to develop magical powers. The story follows Logan, a shy girl who craves adventure with the power to heal herself and others; Harlow, a sarcastic tough girl who develops premonitions; Birdy, the geeky bookworm who can read minds; Lu, a blonde hipster with the power of shapeshifting; Juliet, an innocent girl who has the ability to fly; Keira, a girl who can teleport anywhere, who seems to be hiding something dark; and Taylor, the invisible-powered tomboy who falls for someone with an even darker secret. As each girl deals with family, friend, and boy drama, something big and something evil is making its way to them- something that could kill them all, or worse; destroy the entire world.
