I'm not trying to double your Jonathan Edward's reading volume, but one book by him that I always like to recommend is "The End for which God Created the World". It's definitely a book you may need to read more than once though. If you are looking for books that edify, I agree with Pilgrim that you may want to remove "Mere Christianity" from your list. On the other hand, "Mere Christianity" is recommended and talked about so much in Reformed circles (for a reason I haven't ever really understood), that it might be good to read it just so you can discuss with supporters of the book the many problems in Lewis's theology. Marie mentioned anything by A.W. Pink, but, if I had to choose one, my personal recommendation would be "The Sovereignty of God".
