Book excerpt: When Angela Shilliday discovers she isn't up to the task of authoring the biography of Dr. Andrew Povitch, a Nobel Prize-winning economist, she hires Nell Bane to ghostwrite the book. As they work, Nell begins to learn that her client, who appears to have everything, still wants more. Angela, in fact, wants everything and will apparently exceed all boundaries to get it. As the writing project proceeds, Nell Bane finds herself a reluctant witness to human ambition, deceit and grief. Ethics, psychology and intrigue are the hallmarks of a Nell Bane novel.
