The Graves: The Vanishing

At thirteen years old Henry Graves never had any plans of becoming a secret agent, nor did his twin sister Elizabeth for that matter. But everything was about to change. When their parents were abducted in the dead of night, up and vanished without a trace, it would be up to the two of them to find them again. Luckily, the most secretive organization the world has ever known has taken them under their wing. And if they ever want to see either of their parents again, they're going to have the most difficult test of their young lives ahead of them.
