So I guess I'm cheating here when I recommend two recently read books for love at first sight scenes.

Roses by Leila Meacham is fabulous. Granted, I'm not done yet, but I love the main characters and there's a definite love triangle. The dust jacket said that it was written in the style of Gone With the Wind and The Thorn Birds. It was right!

I know I've already gushed about this series, but I'm a total sucker for the Katniss/Peeta/Gale love triangle in The Hunger Games. And there is a love at first sight scene in the first book- you just don't realize it when you read it. It's soooo sweet!
Are there any other love triangle books you'd recommend? Happy Valentine's Day, everyone!
