The killing sea - Richard Lewis

Despite being from opposite sides of the world, Ruslan and Sarah are brought together in the aftermath of the tsunami. Sarah is sailing with her family when the giant wave hits their boat, flinging the family apart. Her mother is killed, and alone with her younger brother, Sarah begins to search for their missing father. Ruslan's father, a mechanic, was supposed to have been working on a ship when the tsunami struck, but all is not as it seems. It turns out that he had been using the job as a cover to travel to the rebel area of Bergang. In order to find his father, Ruslan must therefore undergo a dangerous journey through rebel territory. In the midst of widespread destruction, Sarah and Ruslan's paths cross, and their lives are changed forever.
