My book, Evil by Design is now on sale! Initial reviews are very positive, with people like Alan Cooper ("The Inmates are Running the Asylum") and Don Norman ("The Design of Everyday Things") both saying how much they like it. You can find out more at evilbydesign.info.
You can download a sample chapter FREE (2.5Mb PDF) – all I ask in return is that you tweet about it. If you like what you read, get the book on Amazon USA, or Amazon UK. The paper edition is almost as cheap as the e-book, and it's a full color high quality book, so I really suggest you buy that version.
