I am about as excited as I could be by a new book. This is One Midsummer’s Day: Swifts and the Story of Life on Earth, published by Jonathan Cape on 1 June 2023. I feel that somehow I have been planning to write this book all of my life. Truth be told, it has taken me 16 years to get it down! Yet I am so delighted with the results. Thank you everyone – and there are many – who helped me finally to get it done.
