I love, love, love any cookbook that involves baking. Just got a new one that I read cover to cover, only to be disappointed by the first three recipes I tried. It was "The Back in the Day Bakery" cookbook by Cheryl and Griffin Day. The photos are great (though they are missing a few for the recipes which kills me!) and the narrative is fun. The authors seem tremendously likable and seem to have a true passion for their craft.
I first tried their hot cocoa recipe and it was bitter. It took a lot of doctoring before it was drinkable. I also tried their marshmallow recipe which was ok (Martha Stewart's is better). It was a bit too gummy and obtained all of it's taste by the powdered sugar you roll it in. Finally I tried their "most popular" white cupcake. It was dry and tasteless.
