As Christy undertakes an adventure into a wondrous and dangerous new world full of strange aliens and advanced technology, she'll need to trust her instincts and rely on the unique abilities of her friends if she wants to lead everyone safely home.

Book 3: At the Portal's End

It seems like each time Christy goes to the Empty World, more goes wrong. But she still can't stay away.
