This series is filled with SO MUCH AWESOME! Like the Black Dagger Brotherhood series mentioned above, each book is about a different brother. Each brother has a very distinct personality which allows for a whole new type of fantasy for each book! Then you add in that they work for a hospital (well...a Demon hospital) which means they're good at heart and whatnot. Oh and they all have above average penis size and special erotic demon powers since they just so happen to be Incubus Demons. You can't go wrong with that!
I HOPE YOU ENJOY MY RECOMMENDATIONS!!!
