Survival is written in blood.
CYCLUS is a near-future speculative thriller (50,000 words) in which a mysterious virus threatens to reboot humanity, and survival is determined by blood type.
When a biological phenomenon known as the Umbra forms over a remote mine in the Brazilian rainforest, a classified research team vanishes. The anomaly behaves less like a disaster than a system—adaptive, selective. Alive.
Stacy Nakano, a cave diver estranged from her late uncle’s mining empire, is drawn back when the Umbra is traced to land she has inherited. As governments race toward militarized containment, Stacy discovers the phenomenon is not an enemy but a recurring evolutionary mechanism—one humanity has faced before and failed to understand.
With the help of Preston Barrows, a cellular engineer who has altered his own blood to survive exposure, Stacy learns the Umbra resets humanity each time it mistakes survival for purpose. As extinction looms, she must choose between destroying the system—or entering it to change its outcome from within.
Blending the existential unease of Annihilation with the scientific rigor of The Andromeda Strain, CYCLUS is a speculative thriller grounded in biological horror, philosophical inquiry, and deeply human stakes.
