Star Trek: Discovery ended a year ago without the trailblazing Paramount+ series spilling the details of its best untold story. Star Trek: Discovery season 5 closed out the saga of the USS Discovery, with Captain Michael Burnham (Sonequa Martin-Green) unlocking the secrets of the ancient life-giving technology of the Progenitors. Discovery also concluded with the wedding of Ambassador Saru (Doug Jones), and flashed forward decades to sync Discovery with the events of Star Trek: Short Treks' "Calypso."
Star Trek: Discovery season 3 soft rebooted the series by jumping to the 32nd century, charting the farthest point of Star Trek's timeline. Between Star Trek: Discovery season 3's premiere and second episode, however, there was a one-year time jump. Commander Michael Burnham beat the USS Discovery to the future, arriving in the year 3188 and meeting her eventual husband, Cleveland Booker (David Ajala). One year later, the USS Discovery arrived and reunited with Burnham - but what happened during that 'lost year' Michael spent with Book?
Star Trek: Discovery Won’t Reveal The Untold Story Of Burnham & Book’s Lost Year
Michael & Booker Grew Closer Traveling The Galaxy Together
Now that Star Trek: Discovery is over, the story of what happened in Michael Burnham and Cleveland Booker's 'lost year' together won't be dramatized on-screen. Michael and Book fell in love during their year traveling the galaxy together as couriers, and there have been hints about their adventures throughout Star Trek: Discovery seasons 3 to 5. But audiences won't be able to see the details of Burnham and Book's voyages with Cleveland's cat and queen, Grudge.
I think that'd be an amazing story. Because that year, I call it "the adventures of Burnham and Book featuring Grudge the Queen", like that specific period of time, I think there was so much growth for Michael Burnham, so much growth for Cleveland Booker. I think that journey inside of that year has allowed them to be the individuals that they've become, that we then meet in the rest of Season Three.
Una McCormack's 2021 novel Star Trek: Discovery: Wonderlands delved into what happened to Michael Burnham and Cleveland Booker in the year before the USS Discovery arrived in the 32nd century, although Star Trek novels typically aren't considered official canon unless directly referenced on-screen in a Star Trek movie or TV series. Regardless, Wonderlands can be considered Burnham and Book's story during the lost year, unless a future incarnation of Star Trek: Discovery as a TV show or movie overrides Wonderlands with its own canon.
