Most angsty on your list are A CANDLE IN THE DARK and FORBIDDEN. I liked both; I liked FORBIDDEN better for reasons unrelated to relative angst.

You might really like UNTIE MY HEART as well, even though HE ties HER up. Their relationship is very complicated. Also, his fabulous fur coat is of the hotness and I love the way Ivory writes about it, even though I think fur coats are kind of gross. If you read it, you will see what I mean.

BLACK SILK is, imo, a very odd book that is excellent but I wouldn't call it fun. For one thing, the heroine's name is "Submit," and she actually loved her late husband--her relationship with the hero of the book is very complex. I should reread that one--I think I gobbled it up too fast back when I first read it, and there's a lot there.

I haven't yet read WILD AT HEART, but it's in my TBR. A TASTE OF CRIMSON I remember was good, but I read it when it came out so my memory of what I liked is very poor--the action was good? I think? A SUMMER TO REMEMBER is really sweet, if I remember correctly--the hero was NICE in many ways, which is rare.

I found THE GENTLEMAN CALLER to be really, really depressing.
