Dear Sister (en Inglés) - R. Thompson

Some losses don't haunt you. They hollow you out.

Kora Vale wasn't supposed to survive.
Her sister Kaley was the one chosen to explore XR-25. a distant, uncharted planet humanity hoped could replace Earth. But Kaley never returned.

Now, years later, Kora's mission isn't about discovery. It's about answers.

Stranded on a savage world of ruins, death, and secrets buried in the soil, Kora must rely on the one companion she never expected to trust, HEX, her sarcastic, black-market-reprogrammed AI. When HEX is reborn in a living alien body and memories from a forgotten race begin bleeding through, everything changes.

What starts as survival turns into something deeper, something human.
Something neither of them were designed for.

But XR-25 isn't done with her yet.
Because Kaley may not be gone.
And if she's alive... she's not alone.
