The Extinction Cycle

 

 

Team Ghost is back—and the Extinction Cycle has entered a new era.

Aethon Books has officially relaunched the bestselling Extinction Cycle series with updated editions, new content, and more stories on the horizon.

It all starts with Extinction Horizon, the novel that launched the saga. The newly released ebook and paperback now include Extinction Kill Zone, a brand-new prequel story featuring Master Sergeant Reed Beckham and Team Ghost on one of their earliest missions—years before the Variants brought civilization to its knees.

And for the first time ever, the entire Extinction Cycle is available to read in Kindle Unlimited, making this the perfect time for new readers to join Team Ghost—or longtime fans to experience the series all over again.

The relaunch is only the beginning. Updated audio editions are in the works, along with new stories from the Extinction Cycle universe, including book 12, Extinction Exiles coming Spring 2027. Plus we're doing some awesome giveaways. Send us a message on how you can get a new limited edition Team Ghost velcro patch for free!
