Used Book – Tara Duncan, Volume 3: The Cursed Scepter by Sophie Audouin, Sophie Audouin-Mamikonian

Tara Duncan, the young magic-wielding princess, must hastily leave Earth for OtherWorld: her mother, Selena, has been injured in an attack. And the cruel Magister, master of the Bloodgraves, whom everyone believed to have disappeared, is back. With the help of an immense and formidable army of demons, he intends to seize the Omois Empire. And perhaps then eradicate the dragon race... Besides, who could resist the power of the Cursed Scepter, which he now possesses and which deprives OtherWorld's spellcasters of their magic? With the Empress and Imperator captured, Tara finds herself alone, at fourteen, at the head of the Empire, to lead a war that is lost from the start. Aided by her friends, Robin the elf, Fabrice, Sparrow the "Beast," Cal the cunning Thief, Fafnir the dwarf, and her great-grandfather Manitou the dog, the young Empress must take every risk. Once again, she must confront Magister, his hordes and spies, as well as his terrifying assassin: the Hunter. Tara Duncan's powers continue to grow, but will her magic be able to stop the demon army from overrunning the Universe?
