Alex re-enters cyberspace, this time winding up in Norse mythology as Vali, son of Loki, where he aims to steal Thor's hammer and possibly free his father.
Alex's meddling in a King Arthur story begins to change the modern world when he prevents Lancelot's and Guinevere's love affair from being discovered.
Believing they're close to finding Matt, Alex steps into Egyptian mythology and finds himself Osiris, king of the gods, with murderously jealous brother Set at his elbow.
