The Thirteenth Reality: The Journal of Curious Letters, is about a thirteen year-old genious named Tick. When Tick discovers a strange letter in the mail, unexplainable things start happening, and only because he decided not to burn the letter. Over e-mail, Tick discovers others that got the same letters and clues. Tick, Sofia, and Paul have no idea what will happen after they've solved the twelve clues and end up on a life-threatening adventure. This book is fun and exciting. It definately makes you think about what will happen to your life depending on your choices, and which choice would've been better. Quantum physics is probably the most unknown science of all, or should I say theory.
