From the start, I was drawn into the story of these two famous people. Some forced proximity leads to a one night stand. Ends up they both find the other makes them feel good, both physically and emotionally.
Seriously, this is one hell of an emotional read. One lost their love to cancer, the other to a sibling. Both know loss and don't want to allow it to happen again. These are two people who know the frailty of life, and think about the unknown of death. The scene were he starts to help her is amazing.
"Let's just get through today, tomorrow will have its own worries."
The author does a great job establishing the conflict, all while taking these enemies to lovers to their happily ever after.
