Extreme Kissing is published in Brazil by Editora iD, translated into Portuguese and called “Sábado sem noção”.
Read lovely reviews on Rosenwine.com, Livromaníaca, Viaje na Leitura and Viver para Ler, with huge thanks to the reviewers! The reviews are in Portuguese, though some of the sites have built-in basic translators.
