Cathy, after you get the Martha Stewart Book (which, btw, is available used on Amazon for as little as three bucks), your next one should be Jennifer Joyce's Small Bites: tapas, sushi, mezze, antipasti, and other finger foods.
While her recipes are very good, and very inspiring, it's her presentations you need to see. And her methods and techniques instructions. Unlike Stewart, who presents those separately, Joyce weaves them in to the recipes---along with all sorts of other tips and aides. All in all, a great book that belongs on the bookshelf of anyone interested in the small plates trend.
