So, as usual, I can't pick just one. But I'm giving the honor of BEST to the entire RUBY RED trilogy by Kerstin Gier. I enjoyed rereading the first two books and the conclusion to the trilogy was excellent. Time travel, romance, great outfits, and some danger splashed in means these are exactly my kind of books.
I need to give an honorable mention to Vicious, just because V.E. Schwab does villains SO WELL.
