Summary
Crash-landed on an alien world crawling with predators, Evelyn expected starvation, violence, and the slow death waiting for the last human survivors stranded far from Earth.
She did not expect Rekosh.
A lethal vrix hunter with too many eyes, too sharp mandibles, and instincts far more possessive than any human should survive. What begins as wary coexistence slowly becomes something far more dangerous as the jungle closes around them and the line between protection, devotion, and obsession begins to blur.
Because once a vrix male bonds—
He does not let go.
And Rekosh has decided Evelyn is his mate.
And the most terrifying part?
She may want him just as badly.
A slow-burn alien romance filled with dangerous devotion, survival, possessive instincts, found family chaos, emotional intimacy, teasing that borders on lethal, and two stubborn idiots falling catastrophically in love beneath an alien sky.

Two hundred years ago, humanity got a new definition - an alien generation ship arrived at the edge of the war ravaged SOL system and our new neighbors, the devonians, became an integral part of the new Human Union.

Summary
I was alone on a spaceship barreling between two galaxies. It had been two years, and our voyage had just begun. I was thriving, actually, as I really enjoyed being alone.
Except I wasn't alone.
I had Aster, my darling robot assistant, who knew my porn preferences better than I did.
And I had Orin, the overkind alien pilot willing to reroute an intergalactic voyage if it made Aster feel less stranded. And willing to put labels on all of my food to remind him what counts as "Breakfast Stuff"
The three of us had a very long way to go.
