This expanded reading order for The Lost Files includes both the individual digital novellas and the print omnibus editions that collect them. Starting with The Legacies in 2011, the series grew to nineteen entries by 2016.
Each novella fills in backstory for a specific character from the Lorien Legacies. Six’s Legacy, Nine’s Legacy, and The Fallen Legacies focus on the surviving Garde members, while later entries like Five’s Legacy and The Navigator explore more peripheral characters and events.
