(2/5 stars) Strange, inconsistent characterization in the main character combined with an extremely predictable plot made this a distinctly un-entertaining read for me.  You can pretty much guess everything about this book from the summary on Amazon:

A decade in the future, humanity thrives in the absence of sickness and disease.

We owe our good health to a humble parasite — a genetically engineered tapeworm developed by the pioneering SymboGen Corporation. When implanted, the Intestinal Bodyguard worm protects us from illness, boosts our immune system — even secretes designer drugs. It’s been successful beyond the scientists’ wildest dreams. Now, years on, almost every human being has a SymboGen tapeworm living within them.

But these parasites are getting restless. They want their own lives . . . and will do anything to get them.

If you want a book about parasites taking people over, I would recommend The Girl with All the Gifts instead.  And in my parasite hobbyist’s opinion, I think the chosen parasite in The Girl with All the Gifts makes more sense than a genetically modified tapeworm.
