Hit List by Jack Heath
Meet Ash and Ben, teen master thieves; stealing for the rich, hiding from the law...and wanted by some of the deadliest men and women in the world. Ashley Arthur and her best friend, Benjamin, are teen thieves working for the billionaire Hammond Buckland, hunting down stolen artefacts and returning them to their rightful owners - for a fee. But when they stumble across an SOS from an imprisoned girl, they realise they're in over their heads. Because there are others looking for the girl. Corrupt governments. Ruthless corporations. Rogue assassins. Suddenly it's Ash and Ben at the top of everyone's hit list...and when you're about to break into the largest intelligence agency in the world to rescue a mysterious stranger, that's a seriously dangerous place to be. Smart, slick and explosive, this is teen crime fiction as its most compelling.
