What does Malcolm Turnbull stand for? In Stop at Nothing Annabel Crabb tells the story of the man who would be prime minister.

Based on extensive interviews with Turnbull as well as those who have worked with him, this is an essay full of revelations. Crabb delves into young Malcolm’s university exploits - which included co-authoring a musical with Bob Ellis - and his remarkable relationship with Kerry Packer, the man for whom he was at first a prized attack dog, and then a mortal enemy.

She asks whether Turnbull - colourful, aggressive, humorous and ruthless - has what it takes to re-invigorate the Australian Liberal Party in the wake of John Howard. She discusses his vexed relationship with Kevin Rudd, and the looming presence of Peter Costello. This is a scintillating portrait by one of the country’s most incisive reporters.
