Waking Gods by Sylvain Neuvel is book two of three of The Themis Files. It has been ten years since Themis, a giant robot found in pieces around the world and painstakingly reassembled, was turned over to the United Nations, founding the Earth Defense Corps, which stands on guard to defend the world against extraterrestrial threats. Though Kara and Vincent, the only people known to be able to pilot Themis, are living well in their renowned positions, physicist and Themis expert Dr. Rose Franklin has struggled to come to terms with her existence, having mysteriously re-emerged five years younger than she was when she died during an explosion at Denver Airport. Her brilliant mind may not have the luxury of such a personal crisis, however, as a second, larger robot suddenly appears in London, intent on destroying Themis on sight. Unless she can figure out what these visitors want, the very future of humanity may be at risk.
