In her well-intentioned first book, First Lady Obama presents the semi-organized tale of the White House Kitchen Garden. Shortly after her husband assumed office, Obama and a class of fifth-graders broke ground on the first food-producing garden since Eleanor Roosevelt's WWII-era "victory garden." Here, Obama details the evolution of the current 1,100 square foot patch, and expands her story to touch on community gardens, farmers' markets, the importance of the availability of fresh foods, and her "Let's Move!" initiative to fight childhood obesity. Organized according to the four seasons, Obama concludes each chapter with timely recipes, including spinach pie, a corn soup to go with freshly harvested summer veggies, linguine with a savory mushroom bacon sauce, and white chocolate-cherry-carrot cookies for a sweet wintry treat. In addition to these "highlights," 40 pages of season-specific recipes are included. Though narrative structure is not Obama's forte (she frequently pauses mid-story to offer tips for home gardeners and advice on how to build a better lunch), this is nevertheless an eye-catching and engaging book. Those looking for a linear story will likely be frustrated, but folks interested in fresh, local food; Obama's "Let's Move!" campaign; and life at 1600 Pennsylvania Avenue will find plenty to enjoy here.
