In this fourth book about Jenny, she continues her entrepreneurial ways with typically amusing results. When Jenny decides to take her own lunch to school instead of buying, a TV program inspires her to make imaginative fare. Seeing the results, her friends decide to give her their lunch money so that she can prepare their meals as well. At first, Jenny is sure that she's on to a good thing; but within a few days she's discovered some sad facts about capitalizing a small business and satisfying the needs of picky consumers. By the time her preoccupied parents discover what Jenny is up to, she's ready to get out of business, if not out of the kitchen. Jenny's fans will find this predictably amusing, the gears of plot and character sliding smoothly into place. Another satisfactory entry in a reliable series. Tight side-sewing and frugal inside margins make this hard to hold and read despite the otherwise attractive format.
