It was the Born In trilogy by Nora Roberts.
Please do not mistake this for a review. This is me lamenting the fact that these books did not affect me as they did when I first read them.
I didn't like any of the heroines this time round. Born in Fire Maggy was a bitch, Icy Brianna was a doormat and Shameful Shannon was almost deliberately obtuse. I did learn something about blowing glass (Maggie), but recipes were not included in the perfect house(not a)wife's book. And how convenient two of the sisters are talented enough artistically to have international showings (Shannon didn't have to suffer for her art at all; her brother-in-law set everything up.)
I loved two of the heroes, Rogan and especially Gray. Gray was a pure delight in book three and it wasn't even his book, lol.
I don't think I'm happy with Nora anymore; her characters (especially the females) are pattern cards for each other and the plots always sound too familiar. Her writing quirks now irritate me and yet, I still buy her. Because, hell, I might miss something!
Okay, maybe I should taper off slowly. I won't buy the mystical trilogies anymore, since they irritate me the most ... and yet I bought the third book of her latest (Blood Magick) and I don't even have the second one! I ended up skimming most of it. Didn't like that heroine either. *sigh*
Oh, I'm so weak.
