Katie's world is shattered by the news that her headstrong and bohemian younger sister, Mia, has been found dead at the bottom of a cliff in Bali. The authorities say that Mia jumped--that her death was a suicide. Although they'd hardly spoken to each other since Mia suddenly left on an around-the-world trip six months earlier, Katie refuses to accept that her sister would have taken her own life. Distraught that they never made peace, Katie leaves her orderly, sheltered life in London behind and embarks on a journey to find out the truth. With only the entries in Mia's travel journal as her guide, Katie retraces the last few months of her sister's life and--page by page, country by country--begins to uncover the mystery surrounding her death. Katie is the sister who has it all: a flourishing career and a smart, loving fianc. Mia is the dreamer: no ties, no responsibilities, no thought for anyone but herself.
