Eight Days: a thrilling British mystery with twists up to the last page...

Two years later, as her relationship with her daughter falls apart, Emily's desperate mother Georgia turns to Slim, wanting answers.

Her eight days missing has changed Emily, so much so that Georgia is unsure the girl is even her daughter at all ...
