Book excerpt: In his role as Australian captain, Michael Clarke has introduced a very different dynamic into the traditions of captaincy. Open, inclusive and articulate, Clarke is a refreshing change from the often gruff and monosyllabic leaders of the past. 2013 has produced his greatest challenge to date - leading an Australian team of uncertain quality against the might of a resurgent England. But underperforming players have not been his only problem, as the sacking of Australian coach Mickey Arthur just days before the First Test at Trent Bridge created shockwaves in the team. Clarke's Ashes Diaries give us a real behind-the-scenes view of the Australian team and the incredible ups and downs of a riveting and controversial Ashes series. Recorded day-by-day, and covering every highlight and lowlight with intelligence and honesty, this is a genuine insight into one of the most rewarding, most difficult and most high-profile jobs in Australia - captain of our cricket team.
