   Summary

   He swallowed hard, trembling but unable to tear his gaze away from the being before him. Fear still rooted him in place, but curiosity—foolish, human curiosity—kept his eyes fixed on the way the moonlight caught the monster’s fur, the faint curl of his antennae, the glint of sharp teeth in the dark.

   It should have been pure terror. And yet… it wasn’t.

   And that fact almost scared him more than the monster did.
