When she is supposed to be having the time of her life in college in California, Leonie loses her mother to breast cancer. After taking her last college course in Buenos Aires, she cashes in her return flight ticket and refuses to go home, erroneously believing that her grief will subside if she avoids her family. Narrating in her own grief-stricken voice, Leonie travels across Argentina, makes friends, and falls in love. She discovers her vulnerability and strength while working at a winery in Mendoza, riding over the treacherous Andes Mountains, and hiking the ancient pilgrimage to Machu Picchu - and, in doing so, slowly begins to heal. Vividly rendered and full of heart, Learning to Whistle will resonate with every person who has ever been forced to venture into the world when they didn't feel ready for it - with or without the guidance of a parent.
