The Blade of the Severed Knot

High atop Mount Kurama, the mist never lifts. Kaede has accepted her post as the guardian of the Shrine, a suicide mission meant to restore her clan's name. When a mysterious, flute-playing traveler named Ren collapses at her gates, she breaks protocol to save him. But as the "Red Moon" approaches, Kaede discovers that the monster she was sent to guard against isn't behind the shrine's great stone gate—it is inside the boy she has begun to love.
