[edit] Story Summary
Shadow of the Giant (2005), by Orson Scott Card, is the fourth and final book of what is being called the Shadow Series (informally referred to as the Bean Quartet), which started with Ender's Shadow, followed by Shadow of the Hegemon and Shadow Puppets. It was published in March 2005. Two additional books in the Ender series are currently being written and will work on tying the Ender Quartet and Bean Quartet together. One will be called Shadows in Flight and will take place after Children of the Mind. The other book, provisionally titled Ender in Exile: Ganges, will deal with some aspects of the Shadow series along with an account of Ender's life before the Speaker series.

At this point, it's known that at least two of Bean and Petra's eggs were implanted by Volescu into other women. One of these has been found, and the book reveals another that is with a woman who believes the child to be Achilles'. At the book's end, this one remains the only one that is still missing.
Meanwhile in conquered China, a belief is spreading that the current government has lost the Mandate of Heaven. Seizing upon this and with some very discreet aid from Mazer Rackham and the International Fleet, Han Tzu (aka Hot Soup), takes control of China, installing himself as its new Emperor. What intent he has now remains to be seen.
Peter Wiggin, Hegemon of Earth, along with Petra Arkanian, comes to visit Alai, who is now the Caliph of the Muslim League. Eventually, the two help Alai realize that he is little more than a glorified prisoner, and that others have been ruling Islam in his stead. After uncovering a conspiracy against him, Alai resolves to take a more firm control of his newfound nation, and to treat the peoples he wrested away from China as actual people, and not as animals as they were being treated before.
The rest of the book deals with Peter Wiggin working to create a world government free of war through his Free People of Earth alliance, while Caliph Alai of the Muslim League and Virlomi, now the virtual goddess of India, have other plans for "uniting" the world under them. Against this back-drop of world political machinations by the former Battle School children is the extremely personal story of Bean, who because of his genetic modifications, finds himself running out of time before he dies, along with his wife, Petra, struggling to find their missing children.
The ending finds Bean and Petra with eight children, the ninth implanted in a woman who believes Achilles is a great man and thinks that their child is his. The woman decides to leave Earth to live in a colony where she can raise Bean's child. Bean takes the children who have Anton's Key (3 of 9) and flies away on a starship provided by the Fleet to achieve relativistic speeds and therefore stay alive long enough to find a cure (although Bean does not think that a cure will ever be found), leaving Petra on Earth. After a heartbreaking letter good-bye, Petra finds out that Peter loves her, and so marries him so that her children will have a father. They also have five children together. It is unknown whether Bean is ever heard from again, although by the time of Peter's death no progress has been made on finding a cure to Bean's giantism. In the final chapter of the novel, Peter speaks with Ender via ansible, giving the Speaker for the Dead all he needs to write The Hegemon.
