Claire Becker was approaching her twenty-eighth birthday on the night she was killed. Her tragic passing, somewhat poignantly, came hours after finding the truth about what really happened to her family, all those years ago.

The precise events of Christmas Day, 1997, would remain a mystery to Claire until the last hours of her life. All those involved that night have a story to tell, and Claire is dead set on uncovering the truth.

After seeing her cousin's face in the paper, Claire sets out on a journey of self-discovery back to her native Scotland. Along the way, she meets the mysterious stranger, Kieran, who takes an unlikely interest in helping her. The man's name, Claire later discovers, is Gaelic for 'Little Dark One'.

While this man with the mysterious past helps Claire find out her own buried truths, disturbing details involving his own past come to light and his shadowy motives start to become clear. As it happens, Kieran also has a vested interest in the events of that Christmas and maybe he's not as innocent in all this as he at first appears - he is after all the Little Dark One...
