About This Book
I have a secret for you: hidden at the far edge of the galaxy lies the Second Foundation, a mysterious place meant to protect all of humanity's knowledge. But no one knows exactly where it is—or if it even still exists. And a young girl with a secret might hold the key, but that's only the beginning.
