A ghost signal turns shipping lanes into traps. An underwater drone swarm holds ships for ransom. A Mediterranean mirage conceals a fleet.

The Siren Code
Abyssal Protocol
The Sirocco Lens
Phantom shipping lanes cut through Arctic fog. An engineered glow conceals cargo in the Pacific abyss. Sabotaged cables distort the timing that keeps ships on course. Jack Calder and the ORRA team follow three threats across the ocean's cold edges and hidden infrastructure, where protecting lives means making the evidence hold under pressure.
Polar Ghost
Hadal Bloom
Dark Cable
From carrier operations in the South Pacific to the South Atlantic and the Indian Ocean, former naval aviator Jack Calder follows a conspiracy that sells silence at sea. Flight crews, investigators and public witnesses must turn instruments, timestamps and unbroken evidence into a defense against manufactured incidents and manipulated rescue windows.
Nimitz Flashpoint
Southern Cross Protocol
Tropic Anchor
From the North Korean coast to Singapore shipyards and a harbor threatened by manufactured panic, Jack Calder follows a market that sells silence by the minute. Covert teams, maritime drones and satellite deception connect three standalone missions with one shared purpose: expose the brokers who turn hidden control into power.
GhostNet: The Broken Conference
Leviathan Run
Black Protocol
Across NATO's eastern and northern frontiers, Jack Calder and Mary Louise Skylion face underwater drones, manipulated signals and a market for stolen time. Three missions reveal how technology, disinformation and financial pressure can move borders without an invasion. Their answer is disciplined operations and proof that cannot be quietly erased.
Blue Wolves
Drone Wall
TRISEC
A deep-ocean recorder exposes a century of buried secrets. A capsule hidden on a Utah ranch connects a quiet town to a lethal Arctic corridor. A stealth narco-sub brings a new threat toward American shores. Jack Calder joins Coast Guard crews in three complete missions where rescue, investigation and control of the oceans collide.
Titanic Deep Switch
Panguitch Cold Corridor
Pacific Viper
Modern conflict moves through trusted channels: relief pipelines, shipping advisories, insurance models and routine paperwork. Jack Calder and a small Pentagon hybrid threat cell follow a global network that turns legitimacy into leverage. Each mission reveals another part of a method designed to survive the people behind it.
Absolute Resolve
Red Sea Chokehold
The Obsidian Network
A downed fighter. A vanished drone. An accusation written before the attack. Across three missions, Jack Calder and the ORRA team confront enemies who manipulate time, perception and proof to turn a crisis into a war. From Iran to the Indo-Pacific, the battle begins long before the first shot.
Downed Sky
Pyrrhic Orbit
First Truth
Satellites reveal intentions. Recovery networks become targeting lists. Trusted evidence rewrites the history of an attack. Jack Calder and Mary Louise Skylion confront a form of warfare that turns the systems protecting nations against them. Across three missions, survival depends on knowing when to trust the data and when to surrender the complete picture.
