What does it take to change history and destroy our reality? The same date, October 31, six different years: Hallows Eve, when the line between the worlds of the living and the dead is the thinnest. The Time Patrol must send an agent back to each day, with just 24 hours for each to defeat the Shadow's plan to disrupt our time line, creating a time tsunami and wiping our present out.

June 6th is the Day of Days. Same date; six different years, the Time Patrol must save our timeline from the shadow by preserving our past to protect our timeline from annihilation. History is made by ordinary people doing extraordinary things. The fact that often history doesn't record the heroics of these people doesn't alter that.

Mike Turcotte, the Special Forces officer who led the fight against the Airlia, which ruled our planet from the shadows for over 10 millennia, has returned to Area 51. Earth has freed itself from the shackles of alien domination but at high cost while winning World War III. He has learned what he believes is the truth about human origins. A truth so devastating he insists it cannot be made public.

Same date; six different years, the Time Patrol must save our timeline from the Shadow by preserving our past.

Many millennia ago, humans, including us, were seeded on 15 worlds by an alien race, the Airlia. We believe we evolved, but the reality is we were bred as cannon fodder for the Airlia’s interstellar war against the Swarm, a viral race whose only mission appears to be the obliteration of sentient life wherever encountered. On some worlds humans realized the truth about their origins, uncovered their hidden alien overlords, and rebelled.
