Harvest [EPUB ebook] 

Physician Matt Wheeler is one of the few who said no to eternity. As he watches his friends, his colleagues, even his beloved daughter transform into something more-and-less-than human, Matt suddenly finds everything he once believed about good and evil, life and death, god and mortal called into question. And he finds himself forced to choose sides in an apocalyptic struggle — a struggle that very soon will change the face of the universe itself.
