Russell, Lisa, Darren and Simon created the Realms as teenagers in the eighties - hacking together a video game at a time when no one really knew what that meant. Years later, Lisa and Darren still work at Black Arts, where the original game has expanded into a dozen spin-off hits. Russell attempted a more conventional career path. And Simon is dead. When Russell gives up his 'real life' and returns to the company, he soon finds himself in a race to save his job, Black Arts' legacy, and the people he's grown to care about. There's a weird glitch in the software: a bug that holds answers to an old mystery, a secret that could change Russell's past - and ruin everyone's future. You is a story of facing dangers, realising that the most obvious path isn't always the best one to follow, and learning that playing a game can sometimes save your life.
