If you could appreciate Screwtape, you'll be able to handle both Abolition and Strength. Abolition is a very short book, almost an extended essay, but packed with insight. I totally agree with CF - between Abolition (as a intellectual dissection) and Strength (as an imaginative expression), Lewis was one of the most accurate prophets of our current cultural situation. The more years I live, the more I see the insights and warnings that Lewis wrote of being borne out in this society. In my opinion, Strength is the most prophetic work of any kind to come out of the 20th century.
Also, if you can get your hands on a copy of the small collection of Lewis' essays called The Weight of Glory, you'll find within a work titled The Inner Ring. This analyzes intellectually some of the themes that are expressed imaginatively in Strength.
