Sierra Six [EPUB ebook] 
The action-packed new Gray Man novel — now a major Netflix film

A TERRORIST BACK FROM THE DEAD. A DEBT TO BE PAID. Before he was the Gray Man, Court Gentry was Sierra Six, the junior member of a CIA action team.In their first mission they took out a terrorist leader, but at a terrible price — the life of a woman Court cared for. Years have passed and now The Gray Man is on a simple mission when he sees a ghost: the long-dead terrorist, but he’s remarkably energetic for a dead man.A decade may have gone by but the Gray Man hasn’t changed. He isn’t one to leave a job unfinished or a blood debt unpaid.——-‘I love the Gray Man’Lee Child’So propulsive, the murders so explosive, that flipping the pages feels like playing the ultimate videogame’New York Times
