About This Book
What if an alien snail had to live inside a super awkward teenager to decide if humans should be wiped out? Ketchvar thought it would be easy—just a quick mission. But being stuck in Tom Filber’s body means facing bullies, embarrassing moments, and even a confusing first kiss. Can the most average kid on Earth change an alien’s mind about humanity?
