Little Sister

Two sisters, Keely and Nina, disappear without a trace. Days later, Keely comes back, covered in blood. It's not her blood. Detective Jonah Sheens knows that she must know what happened to Nina. But before she tells him, Keely insists on telling their full story from the beginning. Is she a traumatised young woman, in need of help? Or is she playing a deadly game? Can Jonah find the truth - and the missing girl - before it's too late? . . .
