Started out great…an astronaut can’t get any response from the quickly approaching Earth, with just enough hard science sprinkled in to keep it realistic. Then, before you know it, you’ve spiraled into a cheap B-rated horror flick complete with (SPOILER ALERT!) zombies, of all things. Really?!?! Zombies? That was the cleverest apocalyptic ending to humanity this author could come up with? Dude, the whole Zombie thing has been done to death, and frankly there’s nothing remotely original or interesting about them in this book, either. Save your credit!!
