Discovering a sphere was only the beginning. Living with one is something else entirely... In the near future, much of the globe wages war against the virtaiyu: a high-tech alien race - and humanity's greatest threat. Like all seventeen-year-old males, Kaiba Cassidy prepares for the battlefront and struggles with leaving behind everything he has ever known. Simultaneously, Nassira Arujo works desperately in the Brazilian rainforest to keep her family's refugee camp safe, and Emily Sursten tries to convince herself that the bliss of Australia can last. Kaiba, Nassira and Emily have no idea that their fates are intertwined until each discovers an Elemental Sphere: a mysterious orb that fuses to their bodies and bestows the capability to control an element of nature. But the trio finds that their new powers come with unexpected consequences, and if they are to keep themselves and their loved ones safe, they will have to fight to prevent the elements from falling into the wrong hands while maintaining their humanity in the process... Through the eyes of its three protagonists, Elementals: The Seven Spheres relays a story as powerful and captivating as nature itself about overcoming obstacles, facing unforeseen difficulties, and making the most of your powers-supernatural or otherwise-to protect friends and loved ones. | Elementals by Jared Files, Hardcover | Indigo Chapters
