Books on Christianity

Hello, I am looking for books that you believe are the best summaries of Christianity in addition to or read along with the main texts of your religion/denomination (IE, not just The Bible). These could be books that greatly influenced your walk with Christ or ones you would recommend to someone who is curious to learn more about the Gospel and Christianity but the main idea is to get a list of supplemental readings that go beyond "Just read the Bible". An exception could be for a Study bible you believe offers exceptional commentary and context.

Feel free to list multiple books, I'm hoping to have sort of a top 10 list by the end.
