Chapter 1 — The Drop in Manaus
Rain fell in diagonals over Manaus as Maya Locke stepped off the hydrofoil and into a carnival of smells—diesel, guava, wet rope. Her phone vibrated once: a single green dot on a black map, pulsing from deep inside the Anavilhanas archipelago. It was the tracker she had sewn into Dr. Elias Rocha’s satchel two months earlier, before he’d vanished with the KAIROS dataset—an algorithm rumored to forecast ecological collapse with military precision. Whoever owned KAIROS could decide which forests lived and which rivers died. And in the wrong hands, “forecast” became “weaponize.”
Maya slid through the market toward a bar whose sign read Bar do Cometa in flaking paint. A man waited at a back table, lean as a spear, eyes bright as river glass.
“Rafael Arantes,” he said, extending a hand. “Federal Police—off duty, officially. On duty, morally.”
“Off duty suits me,” Maya replied. “You got my note?”
He nodded. “Your doctor shows up on every rumor. He’s moving with Lobo Norte—ex-military turned logistics cartel. They ferry timber, mercury, and men no one will miss.” He pushed over a folder. Inside: photos of a sleek aluminum launch painted jungle-green, and a woman with a buzz cut and a smile like a knife. “Commandante Serra. She runs their rivers.”
Maya studied the pictures, her pulse steady by force of habit. “Rocha believed KAIROS would save the basin. Serra believes it will name targets.”
Rafael lifted a canvas duffel onto the table and unzipped it: dry bags, sat phone, a compact drone, two rebreathers, and a flare gun with the dignity of a relic. “My boat leaves in ten. If we chase, we chase hard.”
They pushed off under a sky stitched with swallows. Manaus shrank into a smear of neon. Ahead lay braided currents and islands like sleeping alligators. Rafael threaded the channel with the lazy competence of someone who had grown up reading the river’s handwriting.
Night spread quickly. The jungle’s voice rose—frogs, generators, whispers of rain on leaves the size of shields. Maya upped the tracker’s gain; the green dot jumped, then steadied, thirty klicks northwest. “They’re moving slow,” she murmured. “Heavy cargo.”
“Or laying a trap,” Rafael said.
They killed their light and drifted in the black water, listening. Far ahead: the throb of a big outboard. Rafael angled the bow into a shadowed cul-de-sac of mangroves. “We wait. We let them pass, then follow the wake.”
The cartel launch appeared as a darker line within the dark, red instrument lights faint as embers. Maya’s drone rose like a patient moth and caught a thermal view: six bodies aboard, and one hunched figure with narrow shoulders—Rocha. She swallowed hard. “Target confirmed.”
Then the jungle lit itself. A flare hissed up from the cartel boat and blossomed into bloody daylight. Gunfire stitched the water where their hull had been a second earlier. Rafael threw the throttle; the engine howled. Branches clawed at them like angry hands. Maya returned fire with the flare gun, not to hit but to blind, a comet of white burning the night.
They broke into open water, hearts drumming.
“Trap,” Rafael said, grinning despite it. “Good call.”
“Run now,” Maya said, “or we’ll never catch them again.”
They ran.
