The Return to Irithara (Children of the Sun Book 2)

Enoria is preparing for war with Irithara, and the team sans Kaleth are doing the best they can to put a stop to it before it progresses even further. Their plan? Find Mereria, get her help with killing Relioth, and save Kaleth in the process. They've been trying to find the Umbra leader for a month without success, but they will keep going. They have to. If they fail, millions of people may die for no reason. In the meantime, Nira races against the clock to get back to the capital of Irithara to warn the queen about the Aperios. On her journey, she meets an Eternal named Yorin, who not only helps her get to the palace, but also makes Nira realize how little she knows about her home, and her mother.
