My favorite romance read of 2017 was actually published in 2015: The Vintage Guide to Love and Romance by Kirsty Greenwood. It was a hoot. I laughed out loud a number of times and immediately looked for other books by the author. Hope those I found live up to that one.
I also thought The Bourbon Thief by Tiffany Reisz was well-written but kind of disturbing. It was published in 2016.
As for the stories published in 2017, I liked Pretty Face by Lucy Parker
