Warren Gatland's In the Line of Fire is the ultimate chronicle of this summer's remarkable Lions tour to New Zealand - home of the fearsome All Blacks, the double world champions - which culminated in an historic and nerve-shredding series draw.

The book is the Head Coach's wonderfully candid and vibrant record of the withering ferocity, the turbulent peaks and troughs, the triumphs and despairs, of one of sport's toughest challenges.

It gives rugby fans an unparalleled front-row seat with the squad and coaching team during every facet of preparing for and executing a successful tour on the opposite side of the planet, recounting intriguing details on everything from pre-tour planning and strategy, to on-tour experiences, analysis and decision-making.

It all adds up to a thrillingly definitive exposition and post-mortem of a mind-blowing six weeks in the cauldron which forged the mighty All Blacks.
