A dangerous new computer virus is rapidly spreading throughout the world. It is infecting everything, closing down hospitals, airports and even the internet. Twins Troy and Macy are determined to find out who is behind it. But as they piece together clues and overcome terrifying obstacles, they start to realise that there may be more to this than they first thought. With banking systems about to crash and nuclear warheads about to be fired, can the twins save the world in time? Action! Adventure! Danger! This standalone book from Jonny Zucker's Toxic series is a fast-moving chapter book, filled with high-quality black and white illustrations to grab readers' attention. The Toxic series reads are ideal for reluctant and struggling readers who are enthused by short, fast-paced adventure stories. The cliff-hanger at the end of nearly every chapter certainly helps! - from Amzon
