Heart of the Moon is the much-anticipated sequel to Voice of the Ocean, from beloved and bestselling author Kelsey Impicciche.

In trying to save her sister and her siren world, Celeste may have to battle against the very person she is trying to save …

Our favorite pirate crew are back as they navigate a changing world since the events of Voice of the Ocean. Our hero, Celeste, is singular in her mission: to find and rescue her sister.

Along the way, they are kidnapped by pirates (other pirates), forced to fight King Leonidas men, and Celeste comes into her own power as she fights to save the entire Siren Kingdoms. Of course, she remains stubborn and foolhardy the entire way.
