Sometimes a story just grabs you and doesn't let you go. That's how I feel with this wonderful fic. Do yourself a favour and read this.

This story is truly amazing! Every time they posted a new chapter I dropped everything right away. They literally had me on the edge of my seat.

They did a brilliant job with this!
