Zeus is the author of "Gertrude Laponte, A Women of Substance," an historical account of the Laponte family in America's social, political, and economic affairs. Prentice-Hall Inc., signed Zeus to a contract to publish the book exclusively. The contract left the promotion of the book to the discretion of the publisher. Prentice-Hall had originally planned a first printing of 15000 copies and an advertising budget of $15000 for the book. Later, having had second thoughts about the sales potential of the book, Prentice-Hall decided to do only a first printing of 10000 books and reduce the amount of money it had allocated to advertising. In all, Prentice-Hall published a total of 13000 volumes of the book, authorized an advertising budget of $5500, distributed over 600 copies to reviewers, and purchased ads in major newspapers. Zeus alter claimed that the reductions in the numbers of volumes printed and in the advertising budget were evidence that Prentice-Hall had not made a "best effort" to fully promote the book. Prentice-Hall claimed that its reduction came after careful review and was based on the sound and valid business decisions.
