This story made me so happy! I loved that the main characters was a shy, nerdy scientist and the hot, outgoing, ex-seal who pursued her. For the most part this story was fun and light. 
 Hayden is a biochemist and professor. She lost her parents when she was a teenager. Her aunt and uncle took care of her until she went off to college. She was extremely smart but had OCD issues and suffered with anxiety. She works and takes care of her now aging aunt and uncle with no room for fun in her life. 
 Beck comes from a very wealthy family that has not treated him well. He lost his older brother when he was 12 and his parents have chased off every girl he has tried to have a relationship with. He left his family to join the Navy and become a Seal bonding with two of his Navy brothers. He doesn't believe in relationships and he has seen enough in his time of service that he just wants to have fun in life. 
 These two were the perfect compliment to each other. Both are afraid to love, Hayden not knowing how to have fun and Beck happy to show her how to have fun. What starts out as a no strings fun turns into so much more. 
 I loved the journey these two took to starting out as causal lovers to falling in love, the whole time being in denial that their feelings were growing stronger. Despite them not acknowledging the "more" in their relationship, it was really a low angst read. Hayden was so open and didn't play games. Because of her being so open with him, Beck was understanding of her anxiety and would help ease her into situations. It was incredibly sweet and a nice change of pace from the usual stories out there. I really loved the fact that the Nerd got the Hottie in the end. :)
