Cataclysm of the Taken

Cataclysm: A large-scale and violent event in the natural world.
Taken: to Remove someone or something from a particular place.
Combine the two and what do you get?
Tilda is the only one of the Taken to be found alive. But theres a catch. Tilda won't talk about the one who took her and all the other children. After having eight years of her life stolen from her, any normal person would spill everything the moment it was possible.
But not Tilda.
She has a bigger secret to protect than the identity of a murder and kidnapper.
