I put this link on my blog. Thought it might interest people here tho'. You move a marker along a series of scales giving various qualities you're looking for in a book, then the programme suggests a title!
I got a first choice of Crawling At Night by Nani Power (never heard of it) and, among the alternatives, Kitchen Confidential by Anthony Bourdain which, funnily enough, is currently on its way from Amazon… weird or what!
