Summary
Oh, he was in love.
He knew from the things he wanted to give Simon.
An August sky as a frame for a falling star, a set of wings, the infinite itself -whatever that meant.
He wanted to negotiate with the stars, convince them to arrange themselves into something that looked like Simon, just so he could point up and say: that’s how much I love you.
He would have turned himself into snow just to show him how warm a fire can be in winter.Or:
Simon is slowly changing, and Ryland faces the impossibility of holding onto someone who is already fading away. -

Summary
“My name is Grace, you’re in my home, I’m not gonna hurt you-“
“Bullshit you ain’t gonna hurt me. Who are you with? The C.O.I? I’ll kill you before you can put me back in that hellhole!” The man’s hand trembles as he grasps the piece of broken ceramic, keeping it trained on Grace.
“I swear, I swear! I’m not going to hurt you or put you anywhere, I don’t know what the heck you’re talking about. I don’t know what the C.O.I is but I’m not part of it. You’re on Erid, orbiting the star 40 Eridani. Can you please tell me your name?”
He scoffs indignantly. “You think I was born yesterday? There are no stars. There are no planets. They’re dead. All dead. Everybody knows that.”
What?
Or:
Simon’s submarine appears in the orbit of Erid - he and Grace figure it out.
