Four Descendants. Four unique powers. One common enemy. In the heart of Petros, Havanna and her steadfast ally, Quill, embark on a perilous journey to unite with the remaining ones of their kind in order to challenge the malevolent Dormant King. Complicated feelings arise between them, but neither are willing to address it. Upon finding Anara, the abrasive Water Descendant, and Ender, the Fire Descendant and tribal chief, they realize they all have their own struggles, burdens, and clashing personalities. As tensions rise, they must learn to accept their differences and collaborate for the sake of their kingdom. In a battle for freedom and survival, will they be enough to win the war against the Dormant King? This is the second installment of the Hidden Heroes series. It is highly recommended to read book one, The Call of Thunder, to follow the events of the Descendants' journey.
