Olson’s science fiction space opera series The Ungovernable.

Summary: Isolated on Mars, anyone could start going stir crazy… Katya should be on top of the world. She’s overcome a traumatic past and now she’s part of the first permanent settlement on Mars. So why do things feel so wrong? The colonists are confined to a small base on the surface of a hostile planet, so perhaps it’s only cabin fever. After all, she’s got great friends, an exciting career, and an ex-girlfriend who – she’s sure – would do anything to have her back… But with cracks appearing in the relationships between the crew and nothing but empty Martian desert beyond the safety of their domes, it’s far too easy for the mind to drift. And when it does, it can be difficult to tell what’s real, and what’s pure imagination… Past Imperfect is a short story set during Livid Skies, SI CLARKE’s second novel. It’s written for people who enjoy science fiction that challenges their preconceptions. This is a work of neurodiverse, culturally diverse, gender-bendy, socio-politico-economic, drunken-arguments-in-the-pub science fiction – not bang-bang-pew-pew science fiction.

Summary: The Parada had been lost for almost two hundred years before they recovered the ship, drifting in stygian interstellar darkness, and brought her home again. But that was not the miracle. The miracle was that the crew was still alive. That was also the problem. Six crew members went out on the Parada, Earth’s first starship. All contact was lost, and the ship vanished for almost two centuries. When the Parada’s successor found the drifting ship and somehow managed to bring it home, the six crew members were not only still alive but barely older, due to the time dilation effects of near-FTL travel. Their return was a miracle – but it could not be revealed to the waiting world. The problem was, six individuals went out to the stars. More than seventy fractured personalities came back. Psychologist Stella Froud and Jesuit Father Philip Carter were recruited as part of the team assembled to investigate the mystery, and to try and help the Parada’s crew understand their condition and possibly reverse it. What they discovered was a deepening mystery, and very soon they found themselves forced to take sides in a conflict that nobody could have possibly predicted. Their world would never be the same again.
