  "description": "Dezanove foram as vezes que Colin se apaixonou. Das dezanove vezes a rapariga chamava-se Katherine. Não Katie ou Kat, Kittie ou Cathy, e especialmente não Catherine, mas KATHERINE. E das dezanove vezes, levou com os pés. Desde que tinha idade suficiente para se sentir atraído por uma rapariga, Colin, ex-menino prodígio, talvez génio matemático, talvez não, doido por anagramas, saiu com dezanove Katherines. E todas o deixaram. Então ele decide inventar um teorema que prevê o resultado de qualquer relacionamento amoroso. E evitar, se possível, ter o coração novamente destroçado. Tudo isso no curso de um verão glorioso passado com o seu amigo Hassan a descobrir novos lugares, pessoas estranhas de todas as idades e raparigas especiais que têm a grande vantagem de não se chamarem Katherine.",
