A missing memory
(Book)

"When Martha accepts an invitation to teach a cooking class at the Lancaster Senior Center, she meets the eccentric and enthusiastic Lucy Hill, who used to fly top-secret missions during the Cold War. Somewhere between boiling pasta and making cheesecake, Lucy confides in Martha that there's one mission that has haunted her for years. The problem is, the only memory she has from the mission is waking up in a hospital bed, and the words, "the gray lady." Who or what is the gray lady, and what does it have to do with Lucy's top secret mission? Meanwhile, Lucy's cousins are trying to take Lucy's well-being into their own hands, and it looks like Martha and Lucy aren't the only ones trying to learn about Lucy's mission."--publisher.
