The Edge of Me by Jane Brittan
Sanda is 16. Her parents escaped to London after the Bosnian War. One day she comes home to find them gone without a trace. Before she has time to figure out what’s happened, she’s kidnapped and taken across Europe into Serbia where she’s held prisoner. It’s here that she comes face to face with the brutal truth about what her parents really did in the war and where she learns that everything she’s ever been told, is a lie.
