Book: 3 - Tearing it down series THE ZERO-SUM KEY

In the aftermath of his capture and subsequent mandated exile, Kael Solis, the Custodian of the Shadow, must maintain the stability of the Zenith Share from the void. But the system is under attack, not by chaos, but by perfect, verifiable compliance. A brilliant, anonymous cartel known as the Ouroboros Collective is using the Ledger’s own transparency to gain silent, statistical control, threatening to seize the system’s physical assets without breaking a single rule. Kael's desperate counter is a chaotic dive back into the verifiable world, forcing him into a perilous alliance with his uncompromising code specialist, Cipher. As Cipher initiates a catastrophic "Terminal Exclusion" to purge the system's foundational lie—a lie Kael risked everything to conceal—Kael must fight his own allies to save the Ledger from the destruction of its philosophical core. The Zero-Sum Key is the story of Kael's final sacrifice, where he must surrender his identity, his safety, and his trusted AI companion, Seven, to a devastating, silent destruction, all to prove that the only way to save a perfect truth is by embracing the most dangerous, necessary lie.
