My Kindle is an extension of my bookshelves. I prefer to read an actual book but the Kindle comes in handy for travel or to have available in my purse when I end up sitting in a waiting room. I tend to download free books from Amazon if the genre takes my fancy but I have also purchased some books.
Currently, I'm working my way through the Tasha Alexander Lady Emily historical mystery series (Book One shown below). It's light and easy to read, very enjoyable. I highly recommend it.
