Twelve-year old twins, Corey and Ally Taylor, are members of a secret society called The Premony. They possess a random ability to see premonitions of the future up to a minute before the event. The visions teach Corey and Ally to react fast to change the future or follow their vision if they want the same result. Most of the time, the twins experience the visions separately. But once in a while, they make a twin connection and share a vision. A shared vision occurs in Mr. Marty's science class, and Corey reacts in a way that causes a chemical metamorphosis. The twins gain scientific powers. Corey is excited to have new powers. Ally - not so much. She just wants to be "normal." Did Mr. Marty try to harm Corey and Ally in science class? Or was it his girlfriend, Maxie Frost? Are Corey and Ally safe to enjoy the summer with their friends? The answers lead to a battle of powers. Can Corey and Ally win using the Power of Science, the Power of S? Premony Twins: The Power of S has likable characters, fun comedy, cool scientific powers, and a villain, or two.
