Only ten years into the future, society flourishes. This is due to the absence of sickness and disease. Society owes it's good health to a parasite. SymboGen Corporation has developed a genetically engineered tapeworm. Once implanted, this parasite will protect you from illness, boost your immune system and even secrete designer drugs. 
 Becoming more successful than anyone had even imagined, this scientific revolution took over the world. Years later, almost every human being has a SymboGen tapeworm living within them. But something unexpected has happened. The parasites are getting restless. They want to live their own lives. Doing whatever it takes to be in control. 
 As soon as I found out Mira Grant would be releasing a new novel, the first in a new series, I became as giddy as a school girl. Having fallen in love with the Newsflesh series, I knew immediately that I would be reading anything she published. 
 The first thing that stood out to me was that each chapter had a quote from a character within the world of Parasite. If you've read the Newsflesh series then you have come across this before. For those who haven't, know that they only add to the world building. It adds layers to a story very simply without bogging down the novel with too many points of view. For a previous reader, it was very comforting to read a similar format. 
 The science of Parasite may be a bit more than some people can swallow. However, there was the right amount of it. If you only suspend your mind a touch you'll be able to enjoy it to the fullest. There was even one thing that I immediately looked up while reading. Once I did, I discovered how real it was and proceeded to have a small conniption. 
 My only quibble with Parasite is that I didn't fully connect with the characters. Though they seemed genuine, my connection to them wasn't fully concrete. I get the impression that with subsequent novels, this connection will develop more fully. 
 While the end wasn't completely out of left field, I absolutely appreciated it. It isn't a killer of a cliffhanger, but more something that you will remember this book by. Only leaving you wanting to find out what happens next.
