Mab lifted her head in time with the fevered chanting of the Sidhe and let out a scream that somehow blended perfectly with the song.
The sound of that scream pulsed through me like the most powerful music I’d ever experienced, like the hardest rush of adrenaline I’d ever felt.
I couldn’t help it. I drew in a breath and answered the scream with one of my own. As did the Sidhe. Even Butters lifted his voice in a furious shriek.
And then, without conscious command, we were moving, the Sidhe cohort darting forward with unnatural fury and grace. That power that carried them forward wrapped around me, drawing my feet with more surety and dexterity and power than I could have managed alone, and Butters kept pace despite his diminutive stature.
We moved forward together, as lightly as any troupe of dancers, and as we did the formation changed as smoothly as if choreographed. Mab, upon her dark steed, surged forward, through the ranks of armored Sidhe, until she was at the head of the formation, with me behind her and to her left, Butters opposite me, and the Sidhe and creatures of Winter dropping into an arrow-shaped formation behind us. Mab’s hand fell to her saddle and drew forth a long, jagged blade of what looked like ancient glacier-blue ice. She raised the sword as icy vapor billowed around us, the whole cloud flashing and flickering with faelight like a thunderstorm.
