" the edges of the steel blade as Iron glamour flared around her, a maelstrom of deadly power. I saw her lips move, a name on them, perhaps mine, and felt nothing. My glamour rose up to meet hers, cold and dangerous, and our powers slammed into each other with the roar of dueling dragons.
Flashes of images, like broken mirror shards, falling to the earth. Iron and ice, clashing against each other. Rage and hate, swirling in vicious, ugly colors around us. Glamour and pain and blood. "

― Julie Kagawa , The Iron Knight (The Iron Fey, #4)
