Helen Sedgwick's new novel The Growing Season imagines a world in which babies develop not in the womb, but in a hi-tech pouch, meaning men and women can share the responsibilities of pregnancy. She talks to Mariella Frostrup about the questions of sexuality, family and biotechnology raised by her book.

Also on the programme, a report from a writers' pitching competition in York, the joy of imaginary gardens and the latest literary news from Australia.
