A simple favour. A debt to be paid. A threat no one saw coming.    Mitch Rapp owes powerful criminal Damian Losa a favour, and it’s being called in. With no choice other than to honour his agreement, Rapp heads to Syria to stop a new designer drug spreading into Losa’s territory. When he discovers the true culprit – someone with far bigger goals than just Syria – the scale of his mission grows.   But Rapp and his team are operating in an incredibly volatile country where the US has few assets and allegiances shift almost daily. And just one false move would set off an international confrontation that could easily spin out of control and rewrite the world order . . .  Praise for the Mitch Rapp series ‘Grabs you by the scruff of the neck on page one and doesn’t let you go until the end’ Stephen Leather ‘Sizzles with inside information and CIA secrets’ Dan Brown ‘A cracking, uncompromising yarn that literally takes no prisoners’ The Times ‘Vince Flynn clearly has one eye on Lee Child's action thriller throne with this twist-laden story . . . instantly gripping’ Shortlist ‘Action-packed, in-your-face, adrenalin-pumped super-hero macho escapist fiction that does exactly what it says on the label’ Irish Independent ‘Mitch Rapp is a great character who always leaves the bad guys either very sorry for themselves or very dead’ Guardian
