Dawn sat at the foot of Edie’s bed and closed her eyes. She didn’t really need to, but she’d never tried looking for air currents from indoors before, and she figured anything that could help her concentrate would be useful.
She quickly located and understood the air currents in the building itself—there weren’t many of them, considering Gilkey didn’t have air conditioning, so the only air movement was coming from people’s open windows. Today wasn’t hot, so not everyone had their windows open. Still, there was enough for her to get a good idea of the shape of the building and how many people were inside it just from the air currents.
She moved her consciousness outside and looked at the currents that surrounded the building, then the other buildings near it, keeping her focus to campus. She didn’t want to worry about trying to distinguish the shapes of people from the way the currents moved among trees.
