The Phantom's Daughter (Book 2)

After the disaster at the Opera Populaire, Elise and her father are forced to hide in the streets of Paris.
Madame Giry finds them and sneaks them across the sea, to America, where they spend the next 10 years.
Elise has everything she could ever want, but she knows her father is still pining over his lost love Christine, and without her neither of them can ever be truly happy.

Everything changes when Christine and her family come to Coney Island, to sing at the phantom's show; Phantasma.
Soon, Elise realises that she might not be her father's only child, and when Madame Giry and Meg also come to this realisation, it puts everyone at risk, as America has turned Meg into a very unstable young woman.
