The Last Alignment: Cry of the Scorpions (Book 1)

Follow the journeys of five teenagers as they are brought together to fulfill a shared sacred duty. Awbrey, Hudson, Androse, Zander, and Natalye know nothing of this inherited responsibility and very little about the magic that has been passed down for generations in their respective families. With the reappearance of a man named Hektor, however, their loved ones are forced to finally tell them a multitude of truths and expose secrets that were being kept from them.
Awbrey and Hudson are the only two of the five who have a pre-existent relationship. On top of being ripped from their lives, dealing with revelations, and being given stations they didn't ask for, they also have to get to know and learn each other which-for a bunch of sixteen-year-olds-is everything but easy.
