If you want a standalone first: The Returners

Gemma Malley writes YA speculative fiction that starts with a strong what-if and then follows it to uncomfortable places. What if nobody had to die? What if a government decided children were the problem? What if a society tried to cut evil out of the brain and call the result peace? Her books are built on those big questions, but they stay close to young people trying to work out who they can trust.

She studied philosophy at Reading University, which feels like a good clue to the way she thinks on the page. Before fiction took over, she worked as a journalist, edited business magazines, and wrote for publications including Company and The Sunday Telegraph. She later moved into the civil service and held a senior communications role at Ofsted. That background gave her a close-up view of systems, institutions, and the language people use to explain them.

That mix matters.

Malley has said she did not arrive at writing through one dramatic moment. She started with an idea and kept going. The spark behind The Declaration came from reading news stories about possible cures for diseases linked to old age and then following the thought a little further. She has also pointed to a teenage school trip to Prague, before the Iron Curtain came down, where a brief brush with authority left her with a sharp memory of how quickly freedom can vanish. Both ideas feed straight into her fiction.

The Declaration was her first novel for teenage readers, and it remains the book many people start with. Set in a future where adults can live indefinitely on the drug Longevity, it follows Anna Covey, a girl punished simply for being born. Readers tend to come for the premise, then stay for the emotional pull, the tight control of Anna's point of view, and the moral mess around parents, children, and survival. The follow-up The Resistance opens that world out without losing the personal stakes, and the trilogy keeps building from there.

She did not stop with one dystopia.

In The Returners, she turns to reincarnation, historical violence, and the burden of memory. Then the Killables books, beginning with The Killables and ending with The System, go after a different fear. These novels imagine societies obsessed with measuring goodness, ranking citizens, and watching them constantly. Across both strands of her work, Malley keeps circling the same hard questions: who gets to decide what is normal, what people will give up for safety, and what happens when adults build neat systems that younger people have to live inside.

What readers often like most is that the ideas never sit on their own like homework. Malley's stories move. There is romance, chase, secrecy, and plenty of pressure, but the books also keep asking whether a tidy, controlled world is ever worth the cost. Even when she is writing about futuristic drugs or all-seeing technology, the real tension is usually very human. Children want parents. Teenagers want choice. People want to be seen as more than a label.

She lives in South London with her husband and children. That ordinary, grounded detail sits in interesting tension with the worlds she creates, which are often full of panic about the future. Her fiction may be dark, but it is usually driven by a stubborn belief that young people can question the rules they inherit, and sometimes change them.
