I keep remembering other books I loved last year.
The People of the Book by Geraldine Brooks. March is still my favorite book of hers (it deserved the Pulitzer it got), but this story of how people of different faiths and cultures preserved a remarkable Jewish manuscript for 600 years is marvelously moving.
Rethinking Thin by Gina Kolata. The science of losing weight is surprisingly interesting, at least as related by this NYT columnist.
The Black Tower by Louis Bayard. This historical novel about what may have happened the French Dauphin is simply wonderful. I even said so in print.
