I really like the way Kirsten Birkett laid out this book... it flows really well and is just the right length for me. It doesn't go into SUPER detail but it does go into enough detail for you to get the whole picture of what was going on around Europe, in what order, and who the big players were. I now feel like I have a much better idea in my mind about what was actually happening in the world around the time of the reformation, both in the church and in the wider political arena.
I haven't finished reading the 'bonus classics' yet but I will. I swear I will. It will just take me a while. Not light reading.
