I want to buy a book for a Christmas present. I heard it serialised on Radio 4 earlier this year and just can't think of the title. I have tried Google but don't have enough information.
One episode I listened to was about swifts and how they sleep high in the sky. It was fascinating to listen to. There were other episodes which were on a nature theme but the bit about swifts stood out.
If anyone can help me with it I would be very grateful.
