John Brown, senior music student at the University of Illinois, is bequeathed a strange leather book by his grandfather. He soon discovers that the book is a compendium of magical portals to other worlds and is thrust into solving the mystery of his developing mental powers while doing his best to avert a major war with possibly world-ending consequences. Jon is assisted on his quest by two new friends: Mandy Blackthorn, a beautiful ranger of the forests, and Alison d'Ambrose, a powerful magic user. To save their own lives from demons, they must unravel the mystery of the war; they must find out who is behind it and why. But their troubles have just begun. Ultimately, they must face both the Arch-devil Dispater and the Goddess of War, Morrigan - an explosive combination with their souls at stake. Invoking both Celtic and Finnish mythology, The Trident Trilogy leads readers on a genre-bending adventure that spans the universe.
