Allies — Emery Cole

Morgan's a college dropout with a set of disappointed parents and a part-time job at Shadow Vale Books. Nothing special, right? Especially when she's compared to sister Isabella, who apparently can do no wrong. Nothing special at all, until one day a mysterious codex and an enigmatic ring appear on the bookshelves of Shadow Vale Books. These appearances are intensified when a shadow figure decides to join the party. Matters ratchet up when a hot guy named Azril shows up. A guy who is definitely not human.
