The color version was published by Scholastic Press and released on January 21, 2009. Synopsis The Dungeon and the Parapet The chapter starts with Thorn's dream of Briar, Queen Lunaria, and Lunaria's husband the king at Dragon's Stair, where Thorn is given to her grandmother, Rose Harvestar/Gran'ma Ben, who delivers her to the Great Red Dragon; almost at the same moment, Thorn's parents are killed. Thorn rides the dragon underground into the cavern containing a bright light. The Great Red Dragon asks Thorn to look into the light, whereupon she mentions a frozen waterfall. After trying to see past this, she sees her mother, who asks her to seek the Crown of Horns. Thorn then wakes, and readers learn that Tarsil's soldiers had beaten and imprisoned Thorn and Fone Bone; each losing a tooth in the process. Meanwhile, Gran'ma Ben, on the city walls, throws an interfering Vedu off the wall and two Veni-Yan monks immediately recognize her and re-enter her service. Briar's army arrives at the main gate and Tarsil defies them. In their conversation, Tarsil reveals his facial injures, received from fighting dragons, to Briar, who responds by making her face an image of his former appearance and cuts him into two halves (possibly a reference to the manner of her own death), and declares the attack. Gran'ma Ben immediately takes charge of the city's army and orders the defense. In the dungeon, Fone Bone hears the fight and shouts for the guard; but learns that Smiley and Phoney are in the next cell, while all the guards have all gone to fight. At the wall, Gran'ma Ben oppose the invading hordes of Pawa soldiers and Rat Creatures when the Venu warn her of an attack on the weaker left flank, whereupon she orders them there as reinforcements. She is then pinned down by Pawan soldiers. Thorn tries to break the iron bars imprisoning herself and her friends, but fails. Fone mentions that in using the Crown of Horns, Thorn might destroy both the Locust and herself; whereupon she promises not to use the Crown of Horns. Taneal, a prophetess-like child featured in the previous collection, brings them a hammer by which to break
