I absolutely LOVED These Violent Delights and it's sequel, Our Violent Ends. Based off of Romeo and Juliet (but with gangs), it's a great historical enemies-to-lovers romance set in 1920's Shanghai. I loved the strong female main character and engaging plot, as well as the political elements that are sprinkled throughout. It was incredibly well written, and still managed to have surprising plot twists, despite it being a retelling. I'll definitely be reading it again sometime soon.
