The Lorien Legacies main series consists of seven English-language novels from I Am Number Four (2010) through United as One (2016). This reading order also includes international editions that were published during the series run, including Portuguese, Dutch, and Spanish translations.
The series follows a group of alien refugees from the destroyed planet Lorien as they develop superpowers on Earth and fight against the Mogadorians who wiped out their home world. I Am Number Four was adapted into a 2011 film, which introduced many readers to the series.
