Douglas Stuart author of Booker Prize winning novel Shuggie Bain chooses his favourite book - Train Dreams by Denis Johnson - a short novel encapsulating the history of America in the early 20th century through the life of a lonely man in the forests of the Pacific Northwest.
He's joined by Radio 1 and The Voice Wales presenter Sian Eleri whose choice is I Who Have Never Known Men by Jacqueline Harpman - a dystopian tale of a group of captive women.
Harriett's choice is More Than I Love My Life by David Grossman which examines family trauma through the relationship of three generations of women.
Strong themes of loneliness run through all three choices as well as questions about our humanity.
