Danger and action in a virtual reality world

At fifteen, twins Liz and BJ have it all, money, power and talent. They are computer programmers who specialise in the most complex Virtual Reality games of the twenty-first century. But now an illegal virus in their latest game, Night’s Castle, has left twelve players in niare-filled comas.

With the police one step behind them, the twins set out to solve the problem and clear their name. Their only hope is to enter the terrifying world of their corrupted game in search of clues. But Night’s Castle is no longer the game they created and the creatures they invented have turned against them.

Someone is controlling the game, determined that the twins will not survive.
