Shadow of the Giant by Orson Scott Card fits into the juvenile science fiction genre and was published in 2005. It is recommended for readers ages 16 and up.
Shadow of the Giant is, as far as I know, the last book in the subseries that began with Ender's Shadow. It follows the story of the battle school graduates as they try to gain control of the countries of the earth or as they try to create peace. The book follows the stories of Bean, Petra, and Peter Wiggin the closest. We learn the fate of the embryos that were created for Bean and Petra and the challenges that this fate brings to them. We also learn about Peter's role as the Hegemon and what he plans to do with this title and how it will affect the world. Other Battle School graduates like: Virlomi, Han Tzu (Hot Soup), and Alai are also followed in great detail as they lead India, China, and the Muslim worlds respectively. Overall I really enjoyed this book but it was also a bit difficult. At times I had to think entirely too much, in my opinion, to keep up with the plot line and who all the characters were. This is probably mostly due to the fact that I haven't read the other Ender books for so long that I had a hard time remembering who the people even were. It was a fascinating portrayal of the events that shaped the battle school children in to powerful world leaders. I would recommended this book to anyone who liked the previous Ender books but make sure you at least review the plot from the previous books first.
