This makes reference to the graphic novel. The story starts with Diana as her alter ego Diana Prince and Nemesis taking care of a famous actor in an amusement park, but an accident in a rollercoaster turns things and Diana has to act the heroine, puting herself in danger as the DMA is looking for her. Meanwhile, there's another "Wonder Woman" causing problems making Diana's more diffilcult, but she discovers that this heroine is in fact Goddess Circe. The DMA manages to capture Diana and Circe brings queen Hyppolita back to life telling her that Diana is in a DMA prison, the queen asks to all the Amazons to get ready to combat. This events will start the infamous "Amazons attack"
In my oopinion is not one of the worse stories opf Wonder Woman but it could be better the art by Terry Dodson nothing to complain, except, what came after this story. I think Jodi Picoult didin't have enough time to improve the story so that's why you feel empty at the end.
