This could be a worthy sequel to the much cited "Mythical Man Month" by Fred Brooks. A dozen hot shot programmers set out to prove that a needed Personal Information Manager can be programmed "on time and within budget" despite the ominous warning that so many previous attempts have failed. If you sympathize with the effort, this will be a fascinating cliff hanger. The book needs a glossary, but I noticed that only after turning the last page and looking back.
