Heroes of Both Worlds Book Four: War of Gods

As pressure to sign the Sokovia Accords builds, the demigods are divided. Signing them would mean telling the world their identities and exposing their powers, but remaining in hiding wouldn't allow them to protect the world from further threats.
Hazel, Percy, and Piper agree that the Accords will stop them from what needs to be done, while Reyna, Calypso, Annabeth, and Leo see the benefits of government protection. But with Bucky on the loose and the real culprit still at large, can they set aside their differences or is it already too late?
