The Yeerks have decided to step-up recruitment in The Sharing---but it's not going to be celebrity endorsements this time. It's a cable TV show, one with a lot of interactivity: call-in and Web site....

We never should have done it. But we needed a break. Some time off from the superhero stuff. A chance to act like normal kids. Well - as normal as four kids who can morph into animals, a boy trapped in a hawk's body, and a bright blue alien can be.
