The narrator is Miles, a high school junior, who goes away to boarding school. There, he meets a group of friends, the first group of friends he's had in his life. In his old school he was an outcast, but the sense of belonging he feels at this new school triggers a lot of growth in him. This reminded me of a boy I know, who was an outcast in his previous school, but is now thriving, with a group he belongs to, in a different school. Sometimes small changes can change an entire life.
Miles' group of friends is what many parents would consider "the wrong crowd."
But for Miles, it's the right crowd, because although they introduce him to "booze and mischief" as well as smoking and sex, all of which contribute to the constant threat of expulsion dangling over their heads, they understand him. They look at him, and they see Miles, who he really is, and they accept him. This matters so much more to him than whether the people who include him are "good kids" or "bad kids."
The sun around which the rest of the group revolves is Alaska, a girl with so much charisma that everyone seems to be at least a little bit in love with her. Alaska is impulsive and reckless, as well as troubled, and she barely shares the source of those troubles with her closest friends. In the end, knowing Alaska is the greatest source of pain Miles has encountered in his life, but it's also a catalyst for his personal growth, for him to start forming his own values and viewpoints and interests, beyond the main interest he arrived at the school with: last words of famous people.
I really can not recommend this book strongly enough. I've found a new favorite writer.
Here's a videoletter to his brother that Green made when Looking for Alaska was being challenged. It is the best censorship rant ever.
