I don't really like C.S. Lewis in general. I am reading this series because a friend recommended it to me -- I am particularly interested in the depiction of angels (in relation to a project I am working on).

I think this first novel works pretty well as "science fantasy" but it still is unsubtle and didactic like other stuff I have read by him.

I think stories about space exploration that were written before the space age can be pleasantly whimsical in how they depict it without any of the knowledge that we take for granted about space now. Would it even be possible to write about it in the same way now?

The second novel (Perelandra) sounds really good based on the synopsis -- and this first one laid out enough of a foundation for me to continue with the trilogy.
