The author was Miriam/Mimi Keiffer/Kieffer/Kiefer?, probably published in the early 80s, paperback. Mimi and another woman traded lives and husbands for a short time; it didn’t turn out well. Miriam or Mimi worked in administration at a university in New York.
Could this be “The Life Swap” by Nancy Weber?? It was published in 1974. The author swapped lives, (including partners/husbands) with Micki Wrangler (a pseudonym) who was a college professor. Lots of information out there on this book, which became almost a “cult classic.”
Long shot, but since there’s a bit of overlap in the names and location: the case I’m thinking of is that of Marilyn Peterson and Susanne Kekich, both married to pitchers for the New York Yankees, who swapped lives in the early-to-mid-1970s. I don’t know if either of them ever wrote about it, but the results were…lopsided. Mike Kekich and Marilyn soon parted, but Fritz Peterson and Susanne adored each other and last I checked were still married.
Yes, it must be! I’m 80 and my memory is really bad. I thought it was the other person who wrote the book. I guess I’ve outed her with her real name now; I didn’t mean to. Thank you so much!!
Thank you, but the person above solved it. I had the wrong author.
