Concussed: Sport’s Uncomfortable Truth (Hardback)

Concussed is a call to action, which shows Peters's unwavering passion for the safety of the players in a sport he loves so much. The tension between Peters and professional rugby's top organisations is palpable; there is a real sense of mission in his voice - and vitriol for those who held back the sport for so long. - Observer

'Sam's work is comparable to David Walsh exposing Lance Armstrong. It should go down along with Walsh and the work of someone like Marie Colvin as one of the great pieces of investigative journalism.' - Stephen Jones, Sunday Times rugby correspondent

'Peters is driven, balanced, incredibly bright and appropriately relentless.' - David Flatman

'Sam achieved more in a year than most journalists achieve in their lifetimes. There's no doubt his work saved lives.' - Alison Kervin

'Rugby will never be the same again knowing what we now know. In a time when others obfuscated and trod water, Peters asked the difficult questions and told the terrible stories. Sport needs voices like Sam's.' - Alan Dymock, editor of Rugby World
