There are the rich and there are the very rich, and while the very rich exhibit varied demographic characteristics, the family at the center of Jenny Jackson’s sparkling debut novel, “Pineapple Street,” is of a highly specific sort: the pedigreed, never-touch-the-trust-fund-principal, tennis-playing, old-money-Brooklyn WASP.

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.

It was nearly 20 years ago that I first read A Good Man in Africa. I lived in India at the time, and aspired to write sweeping literary fiction of the sort that featured memsahibs sipping sweet lime sodas against the backdrop of heat and dust.
