11 year old Rory Rooney is prepared for almost anything. His beloved book “Don't Be Scared Be Prepared” has helped him through the times when he's felt anxious and nervous. While the book is filled with facts and what to do in a dangerous situation, the book hasn't readied him for the precarious problem of turning his entire body a broccoli shade of green. Rory is quickly whisked away to an isolated ward to a major hospital in London. He's forced to eat quinoa, be poked, prodded, and examined every day. What is the one perk to being in solitary confinement? No bullies. Until Rory realizes Tommy Lee “Grim” Kominsky (a former classmate) has become green too. At their old school, Grim threw Rory off of buses and confiscated his lunch. The positive… Rory wasn't alone and had other people being hurt by Grim. Now there is no way to hide from the endless torment. He's stuck in a small room with nothing but two cots and an enemy with anger issues. Although Rory is scared, he comes to the intriguing conclusion that he and Grim are superheroes. He believes he can slightly teleport and has a 200% brain. This 200% brain heightens all of his senses. Rory isn't the only one with insane abilities, Grim has special “powers” too. Grim can unlock any door in his sleep. As they sneak out of the hospital each night, they encounter illogical things including, gorillas loose from the zoo, pet penguins, aliens, and another green person, Koko. Each adventure leads them on the quest to look for an answer to their strange sickness. They encounter feats that will require incredible amounts of courage. Will Rory and Grim be cured? Otherwise, they are doomed to living a life of green. Can they convince people that they aren't very different? Or will they be looked down upon eternally? Cottrell weaves a masterfully told tale of friendship and the search for true identity. Rory Rooney searches for a cure, but finds something even better in an unpredictable person. He unlocks the key to friendship.
