This story was different because Lisa and Rick were high school sweethearts and then Rick got Lisa pregnant when she was 16 and things changed. They got married but quickly things didn't work out so they got divorced. However, they raised their daughter together and were always in each others lives. Now their daughter is 18 and going to college. And she's making her mom, Lisa, kick start her new life with going away on a tropical vacation. Except that was all a setup so Rick and Lisa can get back together.
The premise is really sweet and just makes you happy that their love was able to persevere. I also thought the whole coming together idea was great, compliments to the daughter. The only thing I didn't like or understand was how much she fought them getting back together. I just didn't get the why, I thought that was unnecessary conflict when there could've been something else.
I really did enjoy the story though and I think the author did an amazing job at conveying these characters back story and feelings in such a short time. And oh... did I mention it was frecking hot?!?!
