3 and a half stars. 
 I'm kind of bugged. 
 The series is not bad, but book after book, the names changes and the situation remains the same. 
 ***SPOILERS FOR THE WHOLE SERIES AHEAD*** 
 The Hero : dark, tortured, usually soulless, and so alone. He has been abused in the worst ways possible (described in details), everybody hates him, but that exceptional woman (the Heroine) sees trough his defenses and is going to save his soul. Literally. 
 In each book the guy is the embodiment of male perfection, and the heroine is rather plain or otherwise flawed (take your pick: scarred and bad tempered, overweight and shy, socially awkward and clumsy, temporary blind and bitter, and so on). Seems kind of sexist to me. 
 As for the HEA, you'd better love babies, because each couple wishes 5 or 6 of them. 
 ***END OF SPOILERS*** 
 Despite all this, I'm hooked at last until Acheron's story. 
 Eight down and eight to go.
