All of these books are in the vein of Black Dagger Brotherhood and the like. Paranormal elements, romance, erotica, mystery, and thriller elements weave in and out of fun, dark, fast paced stories. I really enjoyed these stories and they kept my mind busy. I think the best part, beyond the hot lemons and fun action scenes, is that there is a great deal of world building involved and an incredible amount of research and planning that Larissa put into these stories. She's built a demon world, but she's also laced in so many religious tidbits and historical facts that it's almost believable that there are humans running around that are actually demons. If they look and love like the Demon brothers, bring it on :)
I'll review number six, Sin's book, Sin Undone, as soon as I finish. I'm looking forward to learning about the sister no one ever though could exist. She's full of piss and vinegar and that's always nice to see!
