The Hues Volume 1: SPECTRUM by Alex Heberling (Paperback, 2017)

Girls will save the world. Sami Raju has been dreaming about a peculiar hexagram her entire life, but never expected a giant holographic version of it to appear floating in the sky over her city. When an alien spacecraft emerges from a wormhole created by the hologram, it is up to her and her six teammates to harness their powers to free their city - and maybe the Earth itself - from the mysterious alien marauders.
