Two sisters, one life-changing journey...There are some currents in the relationship between sisters that run so dark and so deep, it's better for the people swimming on the surface never to know what's beneath ...Katie's carefully structured world is shattered by the news that her headstrong younger sister, Mia, has been found dead in Bali - and the police claim it was suicide. With only the entries of 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. What she discovers changes everything. But will her search for the truth push their sisterly bond - and Katie - to breaking point? The Sea Sisters is a compelling story of the enduring connection between sisters.
