Booktuber and author Jack Edwards made a video on books he would sell his soul to be able to read again. This is that list for my own reference, but others may feel free to partake as well. 

Important information: a few books are added as OPTIONAL in this list. They are: The Picture of Dorian Gray, The Seven Husbands of Evelyn Hugo, and A Little Life. The first two because I already read them, and the third because I have not enjoyed what I read of it. Keep this in mind, and read them if you wish, as they are not a required part of the challenge.
