Shortly after I turned in my new novel, The Stager, my editor sent me a startling black and white photograph of a woman in a chair. The woman is in a state of graceful repose, with long legs extending into strappy black shoes. She is sultry, sexy, and extremely unsettling. She appears to be beautiful even though you cannot see her face because she is wearing a mask. The art director was suggesting updating this image to use as the cover of the book.

And then there is the appendix. You have turned the last page of Lucy Ives’s intricate, darkly funny debut, and a curious timeline appears. Have you missed a plot point or two or 10?

Nina Stibbe’s “Reasons to Be Cheerful” is so dense with amusing detail that I thought about holding the book upside down to see if any extra funny bits might spill from the creases between the page.
