Summary: As the epic trilogy hurtles toward its conclusion, the fight for the future isn’t over yet. It could lead to a new beginning, or it might spell the end for the last vestiges of humankind. The generation ship Forever has left Earth behind, but a piece of the old civilization lives on in the Inthworld—a virtual realm that retains memories of Earth's technological wonders and vices. A being named Lilith leads the uprising, and if she succeeds in setting its inhabitants free, they could destroy Forever. But during the generation ship's decades-long voyage, humanity has evolved. Liminals with the ability to connect with the world mind and the Inthworld provide a glimmer of hope. They'll have to face not only Lilith’s minions, but also the mistrust of their own kind and persecution from a new government as homotypicals continue to fear what they can't understand. The invasion must be stopped, the Inthworld must be healed, and the people of Forever must let go of their past and embrace what they’re meant to become.

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.
