The international bestseller from the Booker-shortlisted author of The Island of Missing Trees and 10 Minutes 38 Seconds in this Strange World. \"One of the BBC\'s \'100 Novels that Shaped the World\'\". \"Every true love and friendship is a story of unexpected transformation. If we are the same person before and after we loved, that means we haven\'t loved enough\". Ella Rubinstein has a husband, three teenage children, and a pleasant home. Everything that should make her confident and fulfilled. Yet there is an emptiness at the heart of Ella\'s life - an emptiness once filled by love. So when Ella reads a manuscript about the thirteenth-century Sufi poet Rumi and his mentor Shams of Tabriz, and his forty rules of life and love, she is ready to look at her life anew. Compelled to embrace change, she embarks on a journey to meet the mysterious author. It is a quest infused with Sufi mysticism and verse, taking Ella and us into a faraway world where faith and doubt are heartbreakingly explored. The Forty Rules of Love is a mesmerising tale of discovery, language, truth and, of course, love itself.
