Kindle users may like to know that Amazon UK seems to have an unofficial sale on a number of e-books, with several as low as 20p, including Winter in Madrid, a spy novel by C.J. Samson set in post-Civil War Spain.
There are several other 20p books in the Bestsellers in Kindle e-books list, including a book of facts from the popular BBC series, QI.
I've never read Winter in Madrid, but I just got myself a copy so I'll let you know how it goes!
Unfortunately, these books are only available if your Kindle is registered in the UK. It's easy to change this in your settings, but doing so may mess up any subscriptions you have.
