This sounds like a story about loss, pain, grief, and love. What I know from the excerpt is that Camden has returned from being deployed. He (and his father) feel that's responsible for his brother Sullivan's death. While Camden's relationship with his brother Xander seems strained, they can at least tolerate each other. That does not seem to be the case with Camden and his father. It sounds like their is a lot of pain and blame in that relationship.
The real question is - what is the backstory of Camden and Willow? There definitely seems to be a strain between them, but I suspect that there's a lot more to their story and I want to know what brought them to the point that they are uncomfortable around each other. What is their history together, besides her being the girlfriend of Camden's brother, Sullivan?
It seems that this is going to be a story about the nuances of the relationships between a father and son, two brothers, and a man and a woman. I look forward to seeing how it all plays out.
