About This Book

Sven’s bike crashes in a spectacular mess of chocolate-anchovy-garlic-mint cake, and suddenly his arm falls right off! But it’s not just any arm—it’s a robotic one that slithers back and sticks itself on again. Now Sven has a shocking secret to face and a wild adventure only he can survive.
