I don’t often recommend nonfiction, but I wholeheartedly recommend this. Helene Hanff was an American writer in New York in the post-World War II era. She wrote to a London bookstore, looking for classics. This book is a collection of the wonderful correspondence exchanged over the next 20 years.  https://www.goodreads.com/book/show/52850170-84-charing-cross-road
