Saito Naotatsu has spent years hiding how he feels.
On the International Space Station, there's nowhere to put distance between himself and the man he's always wanted. Now, with Earth gone and no way home, there's no escaping it either.
The Station was never meant to hold six people forever.
As isolation stretches on and the strain of survival begins to show, every decision carries weigh - and every moment of closeness becomes harder to ignore. What was once a carefully guarded secret is pushed into the open when Turlach, already fraying under the pressure, changes everything between them.
But after that moment, nothing is simple.
Turlach pulls away. Saito is left holding something fragile, uncertain if what they've begun can survive the same pressures threatening to break them all.
Because in the dark, when the world is gone and nothing is certain...
even love can become something to fear.
Dark is the second book in the Expedition 63 series, an MM sci-fi romance about longing, risk, and what happens when the truth can no longer be hidden.
