Dead End — M.R. Forbes

Conor Night, the world's only necromancer, has finally learned what it means to be the world's only necromancer. It's a lesson he wishes he had never received, because thanks to him an ancient wizard with an apocalyptic agenda is back in business, ready to finish cleaning house. Even worse? He's the only one who can stop it. He's been living on a roll of the dice for years, but the stakes have never been higher, and the outcome never so clear: To save the world, he has to die.
