" the old gods were dying "
Shadows had followed Annabeth Chase her entire life. They leaked into her dreams and chased her out of her home, causing her to run into two others, Thalia Grace and Luke Castellan, who had the same shadows. They form a small family fueled by secrets and running.
But after both Annabeth and Thalia are Selected, their shadows follow them to the palace of Olympia, where they will partake in a competition to win the Prince's heart.
The other Selected, which include Piper McLean, Hazel Levesque, and Reyna Ramírez-Arellano, admit to Annabeth that they too have been followed by shadows. Strange dreams plague the Selected, and their shadows seem to be hiding within the people surrounding them.
Just as Annabeth slowly starts to fall in love, several murders occur, and several of the Selected fall as victim. Annabeth soon reveals the biggest truth of all: the Selection isn't meant to find love; it's meant to find those who are different. And once they're found, the world may never be the same.
The Selected were promised love, and they found it, though not in the expected way. But as darkness falls upon the palace and friends turn on each other, can love save them?
Percy and the seven have just defeated Gaea and were summoned to Olympus. The gods wanted to thank them for their bravery and loyalty, and offer each one of them the gift of immortality. Piper, Jason, Hazel, Frank, and... Annabeth all accept the gift. Except for Percy. Percy then feels betrayed and gets into a fight with Annabeth, who uses her new powers in vain on Percy. Percy then disappears while his friends are desperately trying to find him, while trying to break the curse.
