Redirected to Amazon

Hi. When I come to this site, or go to another chapter or something after being on the same page for a while, I am redirected to amazon. It is actually two seprate amazon pages. One is the main page as you go to amazon, then right away it goes to another page where there is only a small box at the top of the page that has amazon's tg library in it.

Does anyone know why this is happening and how to stop it?

Thanks
