It was darker in the tower than any place Devnee had ever been. The dark had textures, some velvet, some satin. The dark shifted positions. The dark continued to breathe. The breath of the tower lifted her clothing like the flaps of a tent, and sounded in her ears like falling snow. It's the wind coming through the double shutters, Devnee told herself. But how could the wind come through? There were glass windows between the inside and outside shutters. Or were there?The windows weren't just holes in the wall, were they?What if there was no glass? What if things crawled through those open louvers, crept into the room, blew in with the cold that fingered her hair? What creatures of the night could slither through those slats?She had not realized how wonderful glass was, how it protected you and kept you inside. She knew something was out there.
