As usual at the beginning of the month, a big list of titles are on sale at Kindle UK. These should be mostly for the month, especially the ones at £0.99, but some may not be, so don't wait if there is a book you really want. Many are repeats, so check carefully before you buy. And, the list, as always, is mostly to my personal taste, together with a few authors I recognize, or that others have mentioned upthread, even if not to my taste :-). All of these are £0.99 unless otherwise indicated. No Smile links in here, because the post will be long enough, but for Smile, just replace the "www" with "smile" in the URL.
