Talismen The Knightmare Knife

On their twelfth birthday, four boys from Earth share the same nightmare about a vicious dragon and a mysterious orange-haired girl. The next day, strange things begin to happen. Monsters appear in school water fountains. A hellhound prowls the city streets. A green man dressed in gold stalks them. The boys discover that they are exiles from the Plain of Imaginings, the land from which all dreams and nightmares come. With the help of a dream warrior named Pratt and his young daughter, Jennifer, each exile must find his talisman, a magical object that can protect them from the green man, who has a dark and secret need for vengeance.
