Fourteen-year-old Ivan is mathematically gifted and obsessed with gaming. Excelling in on-line war games, he falls behind in his studies, withdraws from family and friends, and is manipulative in satisfying his obsession. A mysterious, on-line exchange introduces him to equipment that enhances the gaming experience. Through ivan, his mirror image, he embarks on a quest for the secret of Quaternia, a virtual world where mathematical ideas come alive. With each session on the compelling equipment Ivan becomes less communicative, more introverted, while his avatar becomes more human.

Alarmed by the sight of his son being reduced to a shell, Ivan’s father sets out to uncover the identity of the person behind the dangerous game. His detective work leads to a startling revelation, which he must come to terms with in order to save his son from being syphoned into the virtual Ivan.
