An assassin with a secret, a bookseller with disreputable friends, and an old man with creaking knees and a lifetime of regrets make unlikely heroes, but where magic reigns the most unlikely things come true. In “Assassin,” magic serves Death alone, until tonight. In the short novel Ozan the Hero, monsters prowl the streets of a city while thieves plot and murder beneath them. In “The Enemy of My Enemy,” an unkillable assassin walks the streets of a town under siege. All stories are complete in this volume.
