(Can be read as a stand-alone) A danger to those they have come to respect and love. A challenge between them and sibling rivalry for the title of ruler. Will they stand together to protect, or will their feud pull them further apart? After Apollo and Artemis grew up, a new danger, a new enemy, presents itself. With more people than they ever thought they would end up caring about, the firstborn twins to the king and queen of the sun court have to use their newly-acquired strength and abilities to protect those weaker than them, but with jealousy and tension between the two, can they forget about their feelings and come together to fight? Or will they get each other killed instead?
