Pendragon

The tropical world of Ibara is paradise and the people there are blissfully happy. But it doesn't take Bobby Pendragon long to discover that they are also blissfully oblivious: their leaders are keeping a devastating secret from them.
While Bobby struggles to learn the truth in time to thwart the demon shape-shifter Saint Dane, his ally Mark Dimond is missing. It's up to Bobby's best friend Courtney to find Mark and stop him making a mistake that could change the future of all existence.
