A Symphony of Souls. Earth: The Last Stand

Mysha and her friends, The Five Potens, wield control over elements, space, time, and minds. Yet, their extraordinary abilities may not be enough to thwart the Hubberts - the twenty-seven splinters of the Darkest Demon's Soul - whose mission is to unravel THE SYMPHONY OF SOULS, the supernatural system that binds the destinies of three sister planets: Bliss, Earth, and Inferna.
When dangerous Soulments, fragments of human souls that have acquired magical powers upon death, escape Inferna after centuries of imprisonment, Bliss's rulers dispatch their heirs to Earth as Potens. Each Poten possesses a unique power: the introspective geek from London manipulates space; the reserved American adventurer is the master of elements; the charismatic Australian cricketer freezes time; the mysterious Indian healer tweaks minds; and Mysha, their leader, binds them and their powers into a formidable alliance.
The Hubberts, defying every magical rule, wreak havoc on Earth and seek to turn all humans into Soulments. Mysha embarks on a quest to confront Hubberts' armies, only to be entangled in incriminating doubts, twisted truths, and a hidden enemy who aims to bring her down, along with two worlds. To secure victory, Mysha must unite her friends' powers, and turn herself into the Omnipotent One - an indestructible force beyond the constraints of time, space, mind, and matter. However, if she fails Earth's humans and Bliss's Malaks will become slaves of Infernal demons.
