Nexus: The Second SimCavalier Trilogy: The SimCavalier Trilogies, Book 2

by Kate Baucherel

Books 4, 5 and 6 of the SimCavalier series in a single omnibus edition

The SimCavalier battles for survival in a world teetering on the brink of virtual chaos.

Hacker legend Cameron Silvera–the SimCavalier–has never trusted tech billionaire Jack Sladen. When she uncovers a connection between his new Foundation, a dangerous cybercrime syndicate, and a rogue AI locked away in a high-security prison, Cameron and Jack are drawn into an uneasy alliance. They have the skills to take down their foe, but can they destroy her in time?

A year later, on the eve of the 2048 Olympics, the stakes rise. A breach in the Games' virtual infrastructure points to rigged betting and systemic corruption, forcing Cameron back into the criminal underworld she knows all too well. The hunter becomes the hunted as she faces her foe in a virtual battle where death is all too real.

The balance of global power shifts when the newly-fortified Militia sweeps down the Rockies and takes the United States combined strategic forces by surprise. Machines decide who lives and who dies, but should Cameron believe the simulations or the evidence of her own eyes? As she and her team begin to unravel the truth of a decade-old conspiracy, they become targets themselves. Cameron must call on the unlikeliest of allies to survive.

Nexus includes the original books Critical Nexus, Unstable Realities, and Quantum Breach.

About the author

I'm a scifi nerd whose day job is speaking, writing and consulting on emerging technologies like AI, realities and blockchain. Combining the two, throwing all the technologies I work with into the near future to see what breaks, is enormous fun.

My first books were traditionally published non-fiction, and I still write technical works under my own name and as a ghost writer. When I was asked to co-author a cybersecurity book in 2016, a friend suggested that it might be less dry as fiction. Cameron Silvera and the Argentum Associates team burst into life and the whole process of writing fiction has become a real joy. One of my biggest challenges is making sure that the future technology I invent doesn't find its way into reports for real live clients - but the future is getting closer all the time, and some of my predictions are already coming to life. Bitcoin Hurricane was the first in the SimCavalier series of near future thrillers, and I have a growing catalogue of short stories that include the odd SimCavalier prequel, some standalone tales, and the adventures of Finch, a naive young avian on a rite of passage round-the-galaxy trip.

Inspiration? I've been embedded in scifi since childhood. My first glimpse of the Daleks from behind the sofa pulled me into new worlds, and I never left. As a child I wrote my own Dr Who and Star Wars stories and occasional scripts on an old typewriter in my bedroom, and I read my dad’s collection of Wyndham, Bradbury, Clarke, Heinlen and Asimov before discovering Iain Banks and David Brin, Terry Pratchett and Neil Gaiman. I'm still reading and learning and letting my imagination run wild.
