In Rare Earths cover illustration for the thriller book by Xavier Marce

In Rare Earths

What if every global conflict were connected? Find out in this pulse-pounding action thriller following CNI agent Carla Romero on a desperate race where fiction and reality seem to blur into an explosive mix.

"In a world on the brink of collapse, CNI agent Carla Romero becomes the only one who can see the web no one else perceives. Chasing answers buried in the past, she will uncover a conspiracy that transcends borders, governments, and loyalties. An invisible network not designed to protect us… but to enslave us. Forced to question everything she thought she knew, Carla will launch into a race against time where every truth conceals a new lie. Because some secrets are not kept hidden to protect the world. They are kept hidden to control it."

Brace yourself for a relentless adrenaline rush in an action thriller inspired by today's world headlines. Once again, author Xavier Marcé proves his uncanny ability to anticipate what lies ahead, delivering it through the cinematic, high-octane narrative that never leaves a reader unmoved.

Carla Romero is back in action — more determined than ever — in a thriller where fiction and reality cross a dangerously thin line. Are the conflicts tearing the world apart actually connected?

In Rare Earths is part of the Dystopian Present series alongside The Stone Lotus and Yes, They Will Pass! within the 2nd Line of the XaviVerso — the author Xavier Marcé's transmedia literary universe, where everything is connected.

The World in Flames

Resource Fever

The struggle for control of oil and critical minerals essential for electronics, the military industry, and the energy transition has become a new gold rush of the 21st century. No major power can afford to be left out.

Superpowers out of control

The United States, Russia, and China make no secret of their expansionist ambitions, abandoning the old alliance manuals. Old friendships are crumbling, rewriting the rules of the new international order. There are no longer eternal allies, only shared or unshared interests.

Never ending wars

The conflict initiated by Russia drags on with no end in sight. Analysts are no longer just talking about territory or traditional geopolitics: the Ukrainian subsoil holds uranium, lithium, and potential rare earth reserves that explain the Kremlin's obsession with not ceding a single kilometer of eastern Ukraine.

Rise of Megacorporations

Large technology companies are growing at a dizzying pace, increasingly controlling aspects of society: space exploration, robotics, artificial intelligence, and the military industry. Giants like Xinghe, Ixios, and Aetherion are beginning to have more influence than entire nations.

Border tensions

National borders are becoming increasingly fragile when interests clash. Migratory pressure, drug trafficking, illegal trafficking of people and goods, as well as unauthorized military movements, are all contributing to the escalating tensions, heightening fears of new conflicts erupting.

Ejércitos privados

Las compañías de seguridad privada como se hacen llamar, o de mercenarios, como se las acusa, han encontrado un filón en las tensiones entre diferentes países. Organizaciones como Black Fire han logrado crecer y extenderse por todos los continentes, a pesar de todas las polémicas en las que se ha visto inmersa en los últimos años.
