We're working together on a college class project involving relationships and survival, but my best friend's sister is making it very hard for me to keep up my end of the deal. Shane I'm out of the Marines now and trying to fulfill the promise I made to my best friend, David. His sister and I share a past history, and that lingering physical attraction could also make this promise difficult to keep. Plus, her crazy behavior keeps reminding me of David... making this all even harder. Emma After the loss of my brother, I'm trying to exist in a world where there's no pain because I can't attach myself to anything or anyone. I've learned that attachment leads to loss, and I don't intend to learn the same lesson twice. My plan seems to be working… until Shane starts coming around. When Shane and Emma are forced to work together on a college class project involving relationships and survival, will all of their feelings and behaviors be too much... or will Shane's promise be kept after all?
