A reading plan

So, after picking up on Jess' grand idea, I've listed some of the books that I plan on tackling this year. I'm already reading Heaven and Marriage to a Difficult Man (highly recommend both), and we're working through When Sinners... in our church care groups. Toby and I are also reading through Worldliness, since it's what the singles group that'll be meeting here is reading. I know, though, that there are excellent titles I've not included. So, I call upon ye all - suggestions? Something glaringly obvious that you're embarassed I missed? Some secret gem you've uncovered? Please, enlighten the group!
