Adam Rutherford and Farrah Jarral

As part of Radio 4's Day of the Scientist Harriett Gilbert asks two scientists and broadcasters to choose a book on a science theme. Adam Rutherford chooses Kazuo Ishiguro's dystopian love story Never Let Me Go. Dr Farrah Jarral says when she first read the novella she has chosen - Octavia Butler's Bloodchild - it blew her mind dealing as it does with interspecies procreation and with underlying themes of control and power imbalance. Harriett Gilbert's choice is Piranesi by Susanna Clarke in which the character 'Piranesi' lives in The House populated by endless corridors and statues and The Other.
