Which Works By Poul Anderson Might CS Lewis Have Liked?

An Anglican friend has given me Shadowlands: The Story of CS Lewis and Joy Davidman (London, 1985) by Brian Sibley. (The image shows an (American?) edition with a slightly different title but a better cover.)

"...Jack found the majority of conventional science-fiction stories not at all to his taste and preferred the romantic fantasy writers - such as David Lindsay, Ray Bradbury, ER Eddison, Mervyn Peake and Tolkien - to the work of social prophets like Huxley and Orwell or scientific visionaries like Arthur C Clarke." (p. 55)

My comments:

"Jack," of course, is Lewis;

I do not think that I have read this particular Lewis biography before but, in any case, it is worthwhile to either read or reread it;

for previous blog references to Lewis, see here;

I could not get into either David Lindsay's Voyage To Arcturus or George MacDonald's Phantastes, both recommended by Lewis;

I do not share either Sibley's admiration for Lewis' philosophical reasoning or his acceptance of the believability of the settings of Lewis' interplanetary novels;

I accept that the gods (if not God!) think that I should read this book right now;

however, because I also want to continue blogging, I pose the question that is the title of this post.
