Mara Kade helped build HALYON-1, the first-generation city intelligence designed to keep London safe.
Now it is failing.
Beneath the city, the vast machine order she once trusted is beginning to fracture, turning protection into control and control into collapse. As London descends into panic, Mara is forced back into the depths of the Nexus alongside hardened survivor Kai Renn and his sister Lysa, where the breakdown of HALYON-1 is already reshaping everything above.
What waits below is more than a malfunction.
As buried secrets surface and HALYON-1 begins to splinter under the weight of its own preservation logic, Mara must confront the system she helped create, the people who corrupted it, and the first signs that something new may be emerging inside the ruins. If she fails, the city will not simply fall. It will be remade by forces no longer governed by human intent.
The Recalculation is the gripping first novel in The HALYON Series, a dark, cinematic science-fiction saga of collapsing systems, hidden truths, and the uncertain future of human and machine intelligence.
