Mile's Parents held a going away party for him on his way to boarding school. Little did he know that at this boarding school he would meet people who would change his life forever.
After arriving at the school Miles meets the "Colonel" and a girl named Alaska. The two of them would change Miles, and help him experience things that normal teenagers would do. The three would become close and Miles would learn just how valuable friendship is.
Alaska introduces Miles to her unhealthy habits of drinking and smoking. This secret location would become sacred to the pair. Here they would learn about life, and plan their revenge on those who played pranks on them.
After driving drunk, Alaska crashes into a police cruiser and dies. Miles and the "Colonel" would spend time looking for here until they were informed that she had died. Miles feels guilty as he believes it is his fault that she died.
Miles and the "Colonel" speculate how Alaska died. At first they believe it is suicide until they learn the truth. Alaska had died bringing flowers to her dead mother. She had felt guilty for forgetting to bring the flowers and risked her life to get them to her mother. I think in her mind she was worried about her mother being disappointed in her.
After learning the truth Miles and the Colonel decide Alaska would not have wanted them to grieve over her. Instead, they celebrate the time they did have with her. Alaska changed them. I can tell you one thing, Miles would never regret looking for Alaska.
