First ebook from Christianbooks.com was free. It appeared to only work on the stores own ebook reader but I was able to view the book on my iPad2 iBook reader. What can you say; free ebook and Pilgrims Progress! I already have several printed version but having the eBook version will permit me to read on my iPad.
This is a wonderful book. It will encourage you in your own walk with the Lord, and teach you, by example, how to battle the unseen forces. Christian's walk was not an easy one, and neither is ours. However, with perseverance...comes victory. It is only in the LORD's strength, that any of us will overcome.
