Robert Macfarlane's latest book is his most personal and political yet, asking a question which may sound simple, but which forces the reader to look at rivers in a profoundly different way to simply being matter for human use.

Also telling the stories of three people whose proximity to death is radically altered by their encounters with these rivers, we hope that after listening, your answer to that bold question will be a resounding yes!

Spring is Michael Morpurgo’s first non-fiction book for adults in almost 40 years and the book itself is a portrait of waiting for the seasons to change. In a fascinating conversation he expertly leads us through the landscape he has lived in for over four decades, to share his appreciation of those green shoots, migrating birds and flowing waters that when observed properly, teach us so much about flourishing youth, nurturing growth and why it is so important to have a connection with nature.
