So I am going to give this a go...
My favorite book from last year has to be Dreaming of You by Lisa Kleypas. I read through all of Lisa Kleypas' books and Dreaming of You was the one that stuck because....Derek Craven! He is probably one of the most perfect heroes in the most perfectly imperfect ways. And Sara was one of the most interesting, smart, and non-Mary Sue heroines I have ever come across. It's probably my favorite romance of all time.
