Hounded introduces the character of Atticus O'Sullivan, and his world, an alternate history where magic, vampires, werewolves, gods and other supernatural elements exist (albeit in hiding). O'Sullivan, the last Druid and proprietor of Third Eye Books and Herbs occult shop, comes into contact with many of the supernatural characters of his home city of Tempe, Arizona. He draws his power from the earth, possesses a sharp wit, and wields an even sharper magical sword known as Fragarach, the Answerer.
