What would it take to make you intervene?

When Ella Longfield overhears two attractive young men flirting with teenage girls on a train, she thinks nothing of it—until she realises they are fresh out of prison and her maternal instinct is put on high alert. But just as she’s decided to call for help, something stops her. The next day, she wakes up to the news that one of the girls—beautiful, green-eyed Anna Ballard—has disappeared.

An well written book with an amazingly well written twist at the end. I loved the idea of having the chapters separate into another persons perspective. We have the father, the witness, the PI and the friend which works out incredibly well.

I'll finish writing this review soon.....
