Watch this first:

I think that might be the most intriguing trailer I’ve seen for a book! Plus they’ve even got a site setup for Symbogen. I was going to read this regardless, cause I loved Mira Grant’s previous series, but this just makes me want to read it more!

Here’s the description from 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 tapeworm 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.

Parasite will be released next week on the 29th of October and is £4.82 on (paperback) and $12 on (hardcover).
