Saturation Point
A group of scientists and soldiers are hunted by mysterious enemies in a terrifying new climate thriller from the “Master of British SF”
Doctor Jasmine Marks is going back into hell.
The Hygrometric Dehabitation Region, or the “Zone,” is a growing band of rainforest on the equator, where the heat and humidity make it impossible for warm-blooded animals to survive. A human being without protection in the Zone is dead in minutes.
Twenty years ago, Marks went into the rainforest with a group of researchers led by Doctor Elaine Fell, to study the extraordinary climate and see if it could be used in agriculture. The only thing she learned was that the Zone was no place for people. There were deaths, and the programme was cut short.

Adrian Tchaikovsky
In the realm of speculative fiction, where the boundaries between science and imagination blur, Adrian Tchaikovsky writes with the precision of a biologist and the curiosity of a philosopher. Known for weaving evolutionary theory into alien worlds and giving sentience to the most unexpected of creatures, he crafts stories that challenge not just what it means to be human—but what it means to be alive.
Tchaikovsky’s breakout novel, Children of Time, didn’t just introduce readers to a distant planet populated by hyper-intelligent spiders—it redefined what readers expect from space opera. Bold, cerebral, and emotionally resonant, the book went on to win the Arthur C. Clarke Award, with its sequel Children of Ruin deepening the saga’s exploration of consciousness, cooperation, and survival. In 2023, the Children of Time series earned the Hugo Award for Best Series, a fitting recognition for stories that dare to look evolution in the eye and ask: what if?
