Children Of The Cursed [EPUB ebook] 

In a kingdom in turmoil, people only care for riches and power. As a war breaks out between countries, a godly power is awakening.
Two boys train at the Academy to become Knights of Valor. Best friends, one is filled with light while the other leans towards darkness.
They both have the power to change the world – or destroy it – in their battle for what they believe is right.
