Path of the Paladin - The Books of the Dark Goddess, #4

As a paladin and prime of the Dark Goddess, Ginnevra travels the world with her werewolf companion Eodan, protecting the innocent and destroying evil. Her latest mission: to escort an anointed to the holy city of Abraciabene to receive the highest ordination of the Goddess's servants-the first man ever to do so. Now Ginnevra and Eodan must guide a party of paladins and anointed, all of them at odds with each other, on a monthlong journey through the badlands.
Hounded by evil werewolves and followed by a mysterious creature only Ginnevra can see, her greatest challenge may be from the very man she is sworn to protect.
