This book focused around characters who were involved with MMA. The author definitely did her research and knew what she was talking about out in that respect. 
I liked Skylar’s character. She carried the weight of the world on her shoulder but she didn’t whine about it. 
How could you not like Dom? I also really liked the side characters. The conflict was kind of predictable, and I wish the resolution with the “villain” had been played out more, but it was still really enjoyable.
