Kelley Armstrong is coming out with a novella to go along with her Women of the Otherworld series. Angelic should be due to come out sometime in December and is less than 100 pages. So, if you are a fan of Kelley Armstrong preorder your book. It sounds like it is worth it.
From the book: As a half-demon master of the dark arts, Eve Levine isn’t what anyone would call angelic. That’s exactly why the Fates chose her for the job. She’s their secret weapon against the forces of evil. However after five years, Eve is tired of being the designated rebel of the angel corps, expected to break the rules, then penalized for it. When the leaderless djinn stage an uprising, Eve sees the perfect chance to get herself fired. As she plunges deeper into the demon world, though, she realizes she’s in danger of losing a lot more than her job.
