Mina Satorius, a classmate of Sierra and her crew, is being drawn deeper into the light of the Sorrows' world. Sierra's brother, Juan, isn't quite sure what to do with his band's latest song—it has an actual melody!—but maybe it'll impress his brand-new, out-of-the-blue super-secret crush. And Sierra herself is grappling with the new powers that have made her head of the shadowshapers… and what that means for her life and those around her. The stories of all three collide at the West Indian Day parade as new threats and old foes thread their way towards the shadowshapers in this electric novella set on the eve of Shadowhouse Fall.
