I didn’t think of doing a romantic post in time, but:
Here is a good post on couples that go from antagonism to love, from Random Musings of a Bibliophile, with quotes and pictures. I so agree about Eugenides and Irene. And pretty much the whole list, actually.
Here’s a post on romantic books over at By Singing Light. Ooh, ooh, major thumbs up for Gaudy Night! And several others on the list.
Here’s a post on favorite romantic couples over at Chachic’s Book Nook. On the (rare-ish) occasions I’m in the mood for a contemporary romance, I always look to Chachic for pointers.
