Mark O'Connell, author of the award-winning To Be a Machine, has written a new book which might make perfect reading for anyone in lockdown.

Notes from an Apocalypse was inspired by time he spent on a wilderness retreat in the Scottish Highlands and the concept of apocalyptic anxiety.

He interviewed a range of people who have dark ideas about the future, and what they are doing to prepare for it.

Mark joined us on The Last Word to discuss the book.
