Well-organised, concise and beautifully illustrated
Format: Hardcover, Format: Hardcover
The book can be described as concise, well-structured (being constant throughout its entirety), and quite graphic, aside from the prestigious drawings from Dr. Frank H. Netter, there's also real-life pictures included. The online resources are well used, and they're another tool in case someone want's a quick search instead of going to the index. I recommend this book for anyone who wants to have good knowledge of infectious diseases, without having to go to the more expensive authoritative source (Mandell, Douglas and Bennett's Principles and Practice of Infectious Diseases 9th Ed.), which is also mentioned in the preface.

Good condition Amazing read.
Format: Paperback
Amazing book shipped in good condition which is surprising since it's a paper back and most my books I got from Amazon have at least a little damage from shipping. Definitely pick up this book if you make games.

My 22 year-old grandson was incredibly happy with this gift!
Format: Paperback
I can't write a meaningful review of the content of this book, because I don't begin to understand it, however, it was one of the things my grandson requested for his 22nd birthday, and he seemed thrilled to get it and he tells me it's a great book, so I can say whole heartedly, this is a terrific birthday gift for anyone who's into computer games.
