Christus Victor

Hey Greg,
The whole Christus Victor theme, and the whole thing about Christ coming to set up his kingdom is kind of new and exciting for me.I´m in the middle of the 4 views - nature of the atonement book. Your essay is awesome. After reading it, it was hard to bring myself to read the criticisms from the other authors.
I grew up hearing the only penal substitution side of the story. Your explanation filled a lot of gaps in my understanding of why Jesus died, and answered a lot of questions I had - as does much of your theology, which is why I´m so excited about your work.
Could you reccomend some good books on that topic?
Thanks,
R
