I'll second The Fault in our Stars. It seems modern and romantic. I believe that is my last nomination.
I like the GoodReads link. It gives a synopsis and reasonable reviews as well as a breakdown of how a book is categorized. We all have our own stores we frequent for buying and we have people from all over here. Why just US and UK links JSWolf? What do you have against the frozen hinterland?
I usually base my vote on synopsis and library availability. I am not averse to buying a title, but my budget is limited in comparison to many.
