Summary:

Harry Potter had never used the floo powder. He followed Fred and experienced his first try. Threw a pinch of powder into the flame, shouted the place where he wanted to, tucked in his arms. Harry was so nervous, he got to a place but definitely not Diagon Alley. Then he saw Draco Malfoy.
