Este livro reúne as cartas de Charlie, um adolescente de quem pouco se sabe - a não ser pelo que ele conta ao amigo nessas correspondências -, que vive entre a apatia e o entusiasmo, tateando territórios inexplorados, encurralado entre o desejo de viver a própria vida e ao mesmo tempo fugir dela. As dificuldades do ambiente escolar, as descobertas dos primeiros encontros amorosos, os dramas familiares, as festas alucinantes e a eterna vontade de se sentir 'infinito' ao lado dos amigos são temas que enchem de alegria e angústia a cabeça do protagonista em fase de amadurecimento.

Delaney Escott lives in a world where popularity reigns supreme. If you want to be noticed, social status is everything. The government is run by the Superiors: a very exclusive group of individuals who are virtually flawless. They are smarter than us and stronger than us, and to join their ranks is the highest honor. The Superiors pay an annual visit to the top schools in the nation and evaluate the students, choosing one boy and one girl - the most Popular in the school - to go the Capitol and train for Superiority. Delaney thinks that she's the only one indifferent to (and perhaps even suspicious of) the Superiors, until Caleb Payne, the most popular boy in school, approaches her with a request. He has a task for her, one that he believes she is uniquely capable of completing. And as she helps him, Delaney discovers that the government is hiding many secrets - and that the truth of the Superiors is far from what people believe it to be.
