An enormous robot has come from deepest space, crash-landed on Earth, and followed eleven-year-old Hogarth Hughes home.

Now, young Hogarth has one big friend and an even bigger problem: How do you keep a secret that's 50 feet tall? Especially when a paranoid government agent is on the "alien invader's" trail, bringing with him the full might of the U.S. military to destroy the giant. It all adds up to a rousing adventure that's part metal, part magic... and all heart.
