If you're looking to load up your Kindle there are some good books to be had at bargain prices just now. In no particular order:
A Suitable Boy by Vikram Seth; this is such an enormous book that in physical form it's unwieldy so the electronic version will be easier on the wrists! Size apart, it's a tremendous piece of work.
Dark Matter by Michelle Paver; perfect for this time of year, there's a review of this excellent ghost story here, and good news for Paver fans, Thin Air - set in the Himalayas in 1935 - has just been published.
