From their website:
"We’re offering online customers 25% off the full price of any of the selected fiction titles found here. Titles include the critically acclaimed Swing Time by Zadie Smith; Margaret Atwood’s unique retelling of Shakespeare’s The Tempest; David Dyer’s astonishing debut novel, based on the true story of the ship that saw the Titanic’s distress rockets and did not respond; and last year’s winner of our Readings Prize for New Australian Fiction, which the judges described as a ‘stimulating, thought-provoking and immensely satisfying book’."
