You just can't go wrong with a Harlan Coben novel, can you? I was lucky enough to see this author - one of my all time favourites - when I was in Harrogate, and it was only then that I realised I had somehow missed one of his books - Run Away. I bought it instantly, and had read it by the end of the next day. It's every parent's worst nightmare - a daughter with a boyfriend you don't trust, and then she disappears. It is classic Coben, and I thoroughly enjoyed it.
