I can recommend some popular romance novels:
"Outlander" by Diana Gabaldon
"The Notebook" by Nicholas Sparks
"Pride and Prejudice" by Jane Austen
"The Twilight Saga" by Stephenie Meyer
"Fifty Shades of Grey" by E.L. James
Please keep in mind that these are just some examples and personal preference plays a big role in what one considers a good book.
