Book club reading expectations

For book club I will be reading Unbroken: A World War II Story of Survival, Resilience, and Redemption. Normally this would not be a book that I would select, but I am keeping an open mind about this. I have not began reading the book yet, but based on description, I am expecting that this book will be interesting as it talks about the soldiers life as a child and a teenager and how his life led him to be in the army. I am assuming that he will overcome the obstacle of drifting on the raft and will find himself to safety based on the tittle of the book. Overall I think the book will be about his survival to safety floating on the raft while he thinks about the past and his life until that point.
