Earth, Too [EPUB ebook] 

The crew members of Centaur II return to Earth in the late twentieth-first century after completing over 30 years on an exploratory mission to the first extra-solar planet having life. Since their departure, terrorism and global warming have radically changed the people and environment of their home planet. This story, the conclusion of a trilogy, follows the paths of three of the crew as they strive to uncover what became of their family, friends, and careers, and to rebuild their lives.
