Maida Heatter's Cakes (thanks @heidih)
Rose Levy Barenbaum's Cake Bible (thanks @weinoo)(Hmm. I'm sensing a trend here. Namely, I've always sucked at cakes).
"Un artiste au Grand Véfour," by Guy Martin. I have several others by him, including the massive and gorgeous Le Grand Véfour. I think his, Georges Blanc's, and Roger Vergé's are my favorite French chef's cookbooks. Frédy Girardet gets the Swiss nod.
Let's Eat France!: 1,250 specialty foods, 375 iconic recipes, 350 topics, 260 personalities, plus hundreds of maps, charts, tricks, tips, and ... you want to know about the food of France," by François-Régis Gaudry. Looks goofy, pretty exhaustive, and a lot of fun.
The Cook and the Gardener, by Amanda Hesser. I love narrative cooking books like this, and especially love "a year in....." books that chronicle the changing mood as well as produce of the seasons; this one promises to be a good one.
