Summary:
Twelve-year-old William Wenton is a code-breaking, puzzle-solving genius. He lives with his family in a quiet Norwegian town. He and his family used to live in England, but eight years ago his grandfather vanished and the Wentons suddenly packed up, moved to Norway, and changed their last name! Neither of his parents will tell William why or share the reason he has to keep his talent for solving codes and puzzles a secret. But then a special exhibit comes to the local museum: the Impossible Puzzle. The experts say it is unsolvable, but William's sure that he can crack it if he gets a chance. However, when he does, everything begins to go wrong. Suddenly William is whisked off to a strange school filled with robots, killer plants and kids whose skills are almost as good as his own. But it's also a place filled with secrets. Secrets about William's grandfather. Secrets about what really happened the night William and his father were involved in a serious car crash. And about why William's family had to uproot their lives. But as William begins to look for answers, he learns that there's much more at stake than he could have imagined. And he's left wondering if there's anyone he can trust. -- Book jacket front flap.
