An early morning rush hour in London takes a devastating turn when seven people are killed within a 29 minute period in a coordinated attack. They are all members of a team of investigative journalists.

Famie Madden is managing the desk at the news agency as the reports come in about her friends and colleagues.

As she struggles to come to terms with the events, and puzzles over the motive, she finds that she's been sent a message. Is this a hint of what else is to come, or is it a warning that she will be the next victim?

This is a stunning thriller. I was completely drawn in from the very first page and didn't want to put it down for a moment. I felt I was living Famie's experience in real time with my heart racing and trusting no one! 

The pace is relentless, interrupted and exacerbated by an insight into the terrorist activity. Who will triumph? Who will succumb?

I loved it and continue to be amazed at the versatility of Simon Mayo!

The ideas for his books are brilliant and original - 'Itch', 'Blame', 'Mad Blood Rising' - and it seems he's determined not to remain in one particular genre. I thought the female characters in this book were particularly strong.
