That night we push our cots just a little closer together, and look into each other's eyes in the moments before we fall asleep. When he finally drifts off, our fingers are twisted together in the space between the beds. I smile a little, and let myself go.

I love you," I say. I said that once, before I went to Erudite headquarters, but he was asleep then. I don't know why I didn't say it when he could hear it. Maybe I was afraid to trust him with something so personal as my devotion. Or afraid that I did not know what it was to love someone. But now I think the scary thing was not saying it before it was too late. Not saying it before it was almost too late for me.

This concept could easily have gone awry. Stories about love tend to go that way sometimes. They wander into the realm of cheese and never return, which I think is a shame, because there is a way to write about romantic love without breaking out the Velveeta.
