You don’t have to buy a Kindle to read Broken Spring as an e-book. There’s a free program on the Amazon site that turns whatever you’re using now into a Kindle. I tried it–it works beautifully. The e-book is cheaper than the paperback,and the e-book photos are in color. If you click on this link and then scroll down a bit, you’ll see the “Free Kindle reading app” on the right.
You can buy the book at the same place.
