Blurb

She had no intention of leaving the lab. Then she stole a spaceship.

Chemist Razili prefers logic, samples, and controlled experiments to risk. But the Scozid-neutralizing compound she’s developing keeps breaking apart at the molecular level, and the only solution may be on a planet deep in enemy territory. So Razili does the sensible thing: she steals a spaceship and goes after it herself.

She doesn’t plan on taking a copilot. She definitely doesn’t plan on it being Calyx—the massive and infuriating Trelxak who refuses to stop hovering around her lab.

Calyx won’t force a bond Razili hasn’t chosen, but there’s never a good time to let her know she’s his rhun. Now they’re trapped in a tiny ship, heading toward enemy space, sharing a bed, and trying to survive malfunctioning equipment, alien space bats, and the danger waiting on the other side of the mission.

Razili is brilliant, stubborn, and determined to give the Alliance what it needs to win the war. Calyx understands duty, but he also understands what happens when warriors push themselves past the point of breaking. As the war escalates and every test result matters, he becomes the shield at her back.

One very dangerous romantic field trip with no room for mistakes and no safe distance between them leads to one very inconvenient question: how do you love someone when duty could get you both killed?

The Denchui Alliance

The Denchui Alliance books blend sci-fi adventure, alien-warrior romance, found-family crews, and human heroines who keep surviving impossible odds.

Each romance resolves with its own happily ever after, while the larger Ka’atari conflict, alien politics, and crew bonds build across the series.

Expect protective warriors, dangerous missions, fated rhun bonds, strange planets, open-door heat, and heroines who become much more than rescued passengers.

Good for readers who want:

  • A smart heroine under impossible stakes.
  • Bodyguard vibes in an alien-war setting.
  • Protective warrior heat with action-heavy pacing.
  • Lab danger, warfare questions, and moral pressure.
  • Ka’atari mate-bond certainty.

Maybe skip if:

  • Biological weapon or war-ethics themes are too much.
  • You want cozy, low-stakes sci-fi romance.
  • You prefer lighter banter over pressure-cooker danger.

Can I start with Calyx?
You can read for the featured couple, but the Ka’atari war, crew relationships, and rhun-bond mythology land best in series order.

How spicy is Calyx?
sex that waved goodbye to vanilla a few miles back; check content warnings for book-specific details.

What is the rhun bond?
The rhun bond is the Ka’atari mate-bond signal: a deep biological and emotional pull that turns attraction into recognition, loyalty, and permanent devotion.

Is this more sci-fi adventure or alien romance?
Both. The romance is central, but the series also carries missions, alien politics, enemy threats, found-family crew dynamics, and action-heavy survival stakes.

Does Calyx have an HEA?
Yes. The central romance resolves with a committed happily ever after, even when larger series threads continue.
