The Dream Merchant [signed] [first edition]

Josh Tak is just an average boy. So why is an international corporation so convinced that he is the key to conquering their new market: the past? Drawn into a whirlwind adventure, Josh finds himself in the middle of a nightmare, caught in umaya, a place between dreams and reality. To find his way back, Josh and his friends must follow a trail that takes them through many adventures, to the core of human nature and to the furthest ends of time itself.
