The Invasion is the second companion series to Gateway to the Galaxy, running for nine books. The story shifts focus to a different front of the galactic war, where characters must deal with a direct invasion of their territory. The books run in parallel with both the main series and New Arilion Knights.
Like the other Gateway spin-off, several books share titles with the parent series as the timelines overlap. Yanez uses this structure to show the war from multiple angles. Readers who want the full Gateway experience should read all three series, though The Invasion also works as a standalone military sci-fi story.
