A Seven-Letter Word

Finlay's mother vanished two years ago. And ever since then his stutter has become almost unbearable. Bullied at school and ignored by his father, the only way to get out the words which are bouncing around in his head is by writing long letters to his ma which he knows she will never read, and by playing Scrabble online. But when Finlay is befriended by an online Scrabble player called Alex, everything changes. Could it be his mother secretly trying to contact him? Or is there something more sinister going on?
