For me, personally, all of my favourite reads have the romance genre attached to the stories somewhere. I like this because it's important for the reader to become attached to the book(s) in a way and for me that happens through romance. Also the first book I read when I was a teenager was Twilight by Stephenie Meyer so a romantic book.
My most favourite book series of all time is the All Souls Trilogy by Deborah Harkness (OLDER TEEN/ADULT) because I love the paranormal/romantic element along with the history that comes with those books.
The same thing with The Twilight Saga by Stephenie Meyer (TEEN), 50 Shades of Grey by E L James (ADULT), The Stonewylde series by Kit Berry (OLDER TEEN) etc. They all have different elements but romance is a main part of the story.
The All Souls Trilogy by Deborah Harkness - 5/5 stars
The Twilight Saga by Stephenie Meyer- 4/5 stars
50 Shades Of Grey Trilogy by E L James - 3.5/5 stars
The StoneWylde series by Kit Berry - 4.5/5 stars
