Musing Mondays

hosted by Should Be Reading
This week's musing asks...
What is your favorite romantic book –or book that includes a love story? (an adult romance, young adult, kids’ story, anything)
I've been staring at my bookshelf for 10 min trying to answer this question. I used to read more romantic books, but none of them really stuck with me enough to pick any of them. I always enjoy a good love story mixed into my plots, but this is a hard question! 
I've just realized how many books I've read recently that have no love plot.
I guess I'll go with The Fault In Our Stars by John Green. It's my favorite as of right now.
