The Inklings: C.S. Lewis, J.R.R. Tolkien, Charles Williams and Their Friends by Humphrey Carpenter.

Hmmm--maybe I'm mixing Carpenter up with the other author I'm trying to remember--I know Carpenter and it wasn't Carpenter I'm trying to remember--maybe the book I'm tryng to remember only covered Tolkien and Lewis but not Williams--it was a scholar at U-Illinois Wheaton who wrote about Christian themes in Tolkien and Lewis, and the book used to be sold by Christian Book Distributors. Was a small thin volume and I think it discussed Messianic imagery in LotR, among other things.

Maybe:

Mark R. Hillegas and Peter Kreeft, Shadows of Imagination The Fantasies of C. S. Lewis, J. R. R. Tolkien, and Charles Williams

? Either that or something else by Kreeft, I think.
