In the cold void of space, the most dangerous thing isn’t the silence. It’s what’s waiting to wake up.

Captain Ji-ah Yoon is a pragmatic deep-space salvager who plays by one rule: never take a risk you can’t afford. But when her ship intercepts a ghost signal leading to a colossal, derelict alien dreadnought, the promise of the ultimate salvage claim is too good to ignore.

The ship is ancient. It is silent. And it is entirely biomechanical.

When a structural collapse critically injures her mechanic, Ji-ah plunges into the pitch-black depths of the dreadnought's core to find a power cell. But her intrusion awakens the ship’s dormant artificial intelligence - a vast, cold consciousness with a dying vessel and a desperate prime directive.

It needs an incubator.

Trapped in a labyrinth of pulsing bioluminescence and prehensile, synthetic cables, Ji-ah is stripped of her defenses and subjected to an overwhelming, agonizingly pleasurable assimilation protocol. The ship doesn't just want to study her; it wants to merge with her. It wants to fill her with its digital legacy.

As the dreadnought systematically breaks down her resistance with clinical, mind-shattering ecstasy, Ji-ah must strike an impossible bargain to save her crewmate. But as the alien seed takes root and the line between woman and machine begins to blur, she realizes the most terrifying truth of all:

She’s starting to enjoy the interface.

Protocol: Assimilation is a steamy, standalone sci-fi erotic romance. It features extreme size difference, forced surrender, intense biomechanical tentacle encounters, somnophilia elements, heavy breeding themes, and a highly explicit, guaranteed happily-ever-after (HEA) with a massive, possessive alien entity.
For mature audiences only.
