And there was tough competition too: the newest bid to be the definitive Lewis biography, McGrath's ECCENTRIC GENIUS, RELUCTANT PROPHET, as well as Boenig's CSL AND THE MIDDLE AGES on the Lewis side, and Atherton's and Olsen's books on the Tolkien side. I usually volunteer to be on the award committee but had to sit it out this year, since one of the books I contributed to was a finalist (and, now, winner).* So, obviously, I'm pleased by the news.
Here's the link to the announcement:
Congratulations to all the winners, and all the finalists, and all the nominees.
*I also contributed a blurb to Corey Olsen's book on THE HOBBIT, but that's probably within the bounds and hence no conflict of interest.
