It’s October – so it has to be the Portobello Book Festival. And is so often the case, all but a few tickets have gone; there are a few kept available at the door for each event. Loads of exciting authors, such as Ian Rankin and Michel Faber, will be talking about their work; but there will be some very different events this year. For example, Pamela Gregory and Gica Loening will be discussing their experiences in the Samos Refugee Camp and how a recipe book, ‘Displaced Dishes’, emerged from them. David Calder’s been browsing through the programme.
