Simon & Schuster have packaged these two Sophie McKenzie thrillers really well. The book jackets, designed by Nick Stearn, are superb.

So how about giving both titles together? These are highly topical thrillers with a plotline that involves extremism, terrorism and bombing. But they have a reputation for being unputdownable, so if you give them to a family member prepare not to have much interaction with them once they start reading.
