 Then after that, we'll be speaking with German author Ewald Ahrens about his best-selling novel, Tasting Sunlight, the beautiful, uplifting story of a friendship across generations. If you'd like to quiz Ewald about it, we'd love to hear from you, but please hurry. You can tweet us at bbcwbc or email to worldbookclub at bbc.co.uk. That's worldbookclub at bbc.co.uk. But we do need your questions by the 9th of July.
