Summary
Rainbow is the pinnacle of global counterterrorism — an elite unit composed of the world’s most capable operators, brought together to confront threats beyond the reach of conventional forces. From dismantling the White Masks to navigating the evolving purpose of the Siege Program and the rising influence of Nighthaven, Rainbow operates in a world where the battlefield is constantly changing.
Daniel Ashcroft enters this world as a newcomer with a brilliant mind and a reputation for innovation. His technology and tactical instincts quickly earn him a place among legends, but skill alone isn’t what defines him. At his side is Akari Andrews, his closest friend and trusted partner — someone who knows him beyond the uniform, beyond the mission.
As Daniel integrates into Rainbow, he forms new bonds with operators from across the world, including the elusive Nøkk — a figure as difficult to understand as she is to see.
Rainbow was built to withstand any threat.
But as new dangers emerge and the nature of the fight begins to shift, even the strongest systems can be tested.
And not every enemy announces itself.
