Description

Paperback. ISBN: 0646740156

Portal fantasies usually promise adventure, destiny, and escape.

{ twolonelyheavens }: A STUDY IN HUMAN OBSOLENCE asks a far more unsettling question: what if arriving in another world makes everything worse?

In this bleak, intellectually sharp, and emotionally raw science fiction novel, author Steph Cai dismantles traditional isekai and portal fantasy tropes through a deeply personal transgender lens. When a dimensional rupture tears a close-knit group of friends away from Earth, they find themselves stranded on Fermata, a dying alien world smothered in toxic fog and ecological instability.

Their arrival is not salvation.

It is catastrophe.

The collision between worlds fractures Fermata’s fragile magnetic grid, accelerating environmental collapse and threatening the survival of whatever life remains. Completely unprepared for the hostile conditions, the stranded humans quickly discover that survival on Fermata demands more than courage or optimism. It requires adaptation, transformation, and painful confrontations with identity itself.

Their only ally is a genetically engineered demi-human created by a long-extinct scientific order, a figure as brilliant and capable as they are emotionally distant and openly hostile. As the group struggles against isolation, bodily vulnerability, environmental decay, and one another, old assumptions about humanity, belonging, and personhood begin to unravel.

Combining atmospheric science fiction horror with philosophical introspection, { twolonelyheavens } explores alienation, dysphoria, survival, trans embodiment, and the terrifying fragility of the human body when removed from familiar systems. Steph Cai crafts a world that feels oppressive, intimate, and eerily alive, replacing escapist fantasy with a harsh meditation on adaptation and obsolescence.

Uncompromising, cerebral, and emotionally intense, this is speculative fiction for readers who appreciate queer science fiction, existential horror, ecological collapse narratives, and stories where survival itself becomes a negotiation with identity.

Not every new world is waiting to welcome you.

Some are already dying.
