Here are three links that you can use to purchase Light at the End. You can get this on iTunes or Google Play (if you have an Android). As far as I know, you just have to do a search on iTunes and Google play by title and author to find it there. I hope you’ll give it a chance and write some reviews on it. Depending on what version you get, the pages vary from about 70 to 90. It’s a fast read.
