I forgot about the thermometers. At least, I tried to. By Wednesday, nobody at school was talking about them anymore. Mrs. Adams had replaced them. Life moved on. So did I. Until lunch. Maya and I were sitting beneath our usual tree when Ethan suddenly stood. "I'll be back." "Where are you going?" "Library." "For what?" "Forgot my history book." He walked away. I watched him disappear around the corner. Then something inside me tightened. "Ethan." He didn't hear me. I stood. Maya looked up. "What?" "I need to—" I stopped. I didn't know what I needed to do. I just knew something was wrong. Not dangerous. Not exactly. Just... wrong. I started walking. "Luna?" "Be right back." I followed the path Ethan had taken. I had no idea why. There was nothing unusual.
