Dark

Saito Naotatsu had a secret, though he's done his best to keep the deep yearning for his friend and fellow astronaut under wraps for years. And he'd been successful at it.

The small confines of the Station don't leave room for anything except constant temptation, living in each other's pockets, and reliance on each other. And that was before their weary crew of six couldn't go home.

Turlach, already on edge from the constant stress over the never-ending life or death decisions, ends up turning his friendship with Saito upside down. But Turlach is distant in the aftermath and Saito doesn't know if this problem will be the end of them or not.

If you're going through hell, keep going.
 

Dark is the second book in the Expedition 63 series, an MM post-apocalypse romance about longing, risk, and what happens when the truth can no longer be hidden.
