Romance Book Suggestions

I'm tired of picking up romance book after romance book and either having explicit scenes I don't want, bad writing or tragic endings. Please recommend romance books, series's are cool too (preferred, actually), but I'm just there for the fluff. For example, I really liked Percabeth in PJO.

I'd also rather not have it in a fantasy book (I know that's where the majority of best romances are, which kills me) because there tends to be quite a bit of tragedy and deaths in those. But if there are any which are generally light-hearted I'd be fine with that too.

So, book recs?
