The Sister: A psychological thriller with a brilliant twist you won’t see coming

''I did something terrible Grace. I hope you can forgive me . . .''

Grace hasn''t been the same since the death of her best friend Charlie. She is haunted by Charlie''s words the last time she saw her, and in a bid for answers, opens an old memory box of Charlie''s. It soon becomes clear that there was a lot she didn''t know about her best friend.

When Grace starts a campaign to find Charlie''s father, Anna, a girl claiming to be Charlie''s sister steps forward. For Grace, finding Anna is like finding a new family and soon Anna has made herself very comfortable in Grace and boyfriend Dan''s home.

But something isn''t right. Things disappear, Dan''s acting strangely and Grace is sure that someone is following her. Is it all in Grace''s mind? Or as she gets closer to discovering the truth about both Charlie and Anna, is Grace in terrible danger?

There was nothing she could have done to save Charlie . . . Or was there?

A compelling, gripping psychological thriller perfect for fans of The Girl on the Train, I Let You Go and The Girl With No Past.
