Parasite Positive is a brilliantly dark tale filled with humour, fear and horrid diseases. I absolutely loved this book and should the author ever decide to stop writing, I may just have to hunt him down… Think King’s Misery! In this book, author Scott Westerfeld tells the unsettling tale of a young college freshman, Cal Thompson.

A year prior to the start of this story, Cal was a typical teenage boy interested in nothing much other than girls and partying. Unfortunately (or perhaps, fortunately?) for Cal, he meets a girl called Morgan who, after a night of fun, infects him with a parasite that turns most people into deranged, meat-eating, blood-sucking beings.

Luckily, Cal is not “most people” – instead of succumbing to the parasite, he becomes a carrier. After his one night stand with Morgan, Cal inadvertently passes the parasite on to a number of girlfriends. Cal, now working for an organisation – Night Watch - dedicated to the eradication of the parasite, has to find those women before they in turn can infect others.

When Cal meets the attractive young Lace, he has to be extra careful – just one kiss from him will infect her. While Lace unknowingly aids him in his quest to find the “missing girlfriends”, Cal worries that she will discover his true nature. Can he hide it from her indefinitely? And, perhaps more importantly, can he unravel the conspiracy that he comes to believe exists within Night Watch?

Parasite Positive is a novel that I found almost impossible to put down once I’d started reading it, and it didn’t take me long to read from start to finish. This is most definitely one of the more entertaining and captivating books I’ve read in a long time.

I found the information on various parasites both intriguing and relevant to understanding the story, and was impressed with Westerfeld’s unique style of writing – the man seems to have a knack for bringing a grin to my face while telling me about the horrid things that any given parasite could do to me.

If you’re a hypochondriac or prone to paranoia, then I suggest walking right past this book on the bookshelves. If you enjoy an entertaining, vaguely humorous and informative read, then Parasite Positive is a “must buy”. I would recommend this book to adults and perhaps even older teens.
