Friends, sisters and serial killers all feature in the book choices for this week. Writer and stand-up comedian Athena Kugblenu picks 'My Sister the Serial Killer' by Oyinkan Braithwaite, a darkly comic tale which is as much about sibling rivalry as it is about murder. Nell Dunn's memoir about love and friendship, 'The Muse', is Harriett Gilbert's pick. And Pope Lonergan selects 'African Psycho' by Alain Mabanckou for its challenging portrayal of a frustrated and violent protagonist.
