In Riot, Tillie Cole shows how love can bloom in the darkests of worlds where people are possessions, known only by number and kept under the worst conditions. Riot is truly a dark romance, so you should be prepared for some difficult scenes, but it does a great job of infusing light into 901 and 152's story. 
 While there is some "lightning bolt" love aka insta-love, it's so believable that after everything 901 and 152 go through, that they would find each other and feel something so strong. Some love just can never be forbidden. 
 But love is a weakness in their environment, a liability, and it is certain that the master will use it against them. It's all about the light against the dark (and it can get dark) in this romance and it worked well for me. I loved that even though they are both stripped down to having almost nothing, they still find a way with some help. It's what makes this story compelling. I loved how everything came full circle. 
 This title works well as a standalone but you're probably going to want to go back and read the rest of the series once you are done.
