By V.F. Mason. Callum's HellThis is the 3rd book in the series I've read and while I find them extremely dark and twisted there's something about them that keep me wanting to read more. These books are also filled with pain and torment that almost justifies why the heroes turned into serial killers. Riveting stories that can't really be classified as romances and yet each hero finds the woman who can love and accept him for who he is.
