Quillan Games - D.J MacHale

Quillan is a territory on the verge of destruction. The people have lost control of their own future and the only chance they have of finding a better life is by playing the Quillan Games. Game masters Veego and LaBerge have created a world filled with competition using the people of Quillan as pawns in their computer-driven games. To win is to live like a king, but to lose is to die.
When Bobby Pendragon arrives Quillan is on the brink of chaos and he soon realises that the only way to save this troubled territory is to beat Veego and LaBerge at their own games. But there is more at stake than Pendragon realises. With his opponent none other than Saint Dane, the prize for winning the Quillan games may be discovering the truth of what it really means to be a traveller.
