We had this topic a while ago, but we've all read a lot more books, so I'm hoping for more.  The best for me yet was Black Ice (I know, Claudia!).  He was actually going to kill the heroine.  So, new discoveries?

Karen, I thought the hero in Lorraine Heath's  TEXAS DESTINY  was tormented.  Bren

Rafferty's Bride - the hero was out for vengeance and meant to have her brought to trial for war crimes.

I'm looking for both books right now!  thanks.

I don't know if it was mentioned before, but the hero in "Sword of Darkness" by Kinley MacGregor is quite the tormented baddie.

THE DEVIL'S WEB  by Mary Balogh. James Purnell is so tormented ,he'll drag you down with him.    Bren

I love this kind of guy and the only one I've come across is Texas Destiny by Lorraine Heath.  If one of these new ones everyone is suggesting works for me, I'd be soo happy.  But right now, it's only Houston Leigh :(

Uncertain Magic by Laura Kinsale has a sexy, tormented hero with a mysterious past (even to him). That's the most recent one I've read. I'm looking for something else too, perhaps I should try Black Ice. I've never read Anne Stuart but I'll give her a try once I get through some other books in my pile.

I just read No Way Back by Debra Webb (in anthology Double Impact), I wouldn't call the hero 'tormented' (no history that makes him so) but certainly dark and borderline evil - he's an assassin, and heroine falls in love with him - twice. 

Moon Rise by Anne Stuart, the hero is even darker then the one from Black Ice.

I go back to Black Ice every few months.  He's sooooooooooo bad. bad bad bad.

Off the top of my head, I'd say

The Nightengale Legacy by Catherine Coulter (only complaint is he's a bit over-the-top gothic-y, but definately rather tormented, lol.)

Till Dawn Tames the Night by Meagan McKinney (Vashon started me on a love for bad-boy pirates.  St. Bride in My Wicked Enchantress was also pretty dark - ten years later, he remains one of my favorite heros.)

I wish I could think of more but my mind is a bit foggy right now just trying to remember things I have read. :)

Just ordered My Wicked Enchantress - it was offered here.  thanks.
