When I grabbed this for free off of amazon, I didn't realize that it was a pamphlet version of Schmemann's longer work of the same name. This version was a very quick read and was educational in regards to how Orthodox Christians celebrate Lent; however, it was too brief in the areas that interested me most for me to rate it higher. For instance, I really liked the final section called "How Can We Keep Great Lent?" which explained an orthodox understanding of fasting compared to a Roman Catholic one, prayer, spiritual reading, and changing your life during that time, but that was over in four or five Kindle sized pages. I am sure the longer version of this book is much better.
