There are two authors by the name of Brian Doyle, and it looks like the books of each are correct on GR except the brand new Bin Laden's Bald Spot. It is listed under the author who writes YA fiction. It should be listed under the other Brian Doyle who mostly writes non-fiction. The correct Brian Doyle's other titles include Mink River, The Grail, The Wet Engine, and several other stand-alone works plus anthologies regarding spirituality, and other non-fiction subjects.
Thanks,
