These are not excellent low-fat desserts. They are excellent desserts that are also low-fat. Whether or not I am watching what I eat or cooking for people who are watching what they eat, I always look here first, and no one ever, ever misses the fat and calories. Alice Medrich has done a fantastic job of lightening the dessert tray without resorting to artificial sweeteners, fat-free dairy products, "light" margarine, etc. She emphasizes ingredients of the highest quality, but stretches the fatty stuff (for example, she decreases the amount of nuts in a biscotti recipe, chopping them coarsely to make them go farther and toasting them to maximize flavor). If a recipe can't be lightened successfully, it's not in the book (for example, you won't find shortbread, although somehow, miraculously, she has found a way to lighten whipped cream!).
I have made many of these recipes and have never been disappointed. I'll recommend the Kahlua Fudge Cake, Frozen Hot Chocolate, Lime Cookies (yes, even the handful of non-chocolate desserts are heaven), Michael's Brownies, Fallen Chocolate Torte, Chocolate Hazelnut Biscotti, Genoise, Hot Ginger Cookies, and Buttermilk Chocolate Sauce. I have not tried a recipe that I cannot recommend. You will not be disappointed.
The book is illustrated beautifully and divided, helpfully, according to recipe type (fancy desserts, everyday desserts, individual desserts, etc). It includes nutritional information. The desserts obtain 30% or less of their calories from fat, and although not all are low-calorie, most are (Michael's Brownies, for example, have around 150 calories each and are sinful).
