'I guess you'd better come in and sit down then, Jack. It's time you knew…' Jack is a studious and self-absorbed sixteen-year-old, interested in nothing more than getting top marks at school and the pursuit of his own ambitions. He has no time for games, no time for friends, and definitely no time for his younger sister Mia. But as he continues to isolate himself from the world, Jack is propelled back in time into an imaginary world created by his eccentric grandfather many years before.
