At 8.15 am on 16 May 2004, Vicky Jack stood on top of the world. After seven amazing years, she had fulfilled her ambition to climb the Seven Summits - the highest mountains in each of the seven continents - the culmination of which came when she reached the top of the highest mountain in the world, Mount Everest. In doing so, she became, at the age of fifty-one, the oldest British woman to climb Everest and the first Scotswoman to complete the Seven Summits."The Sky's the Limit" is Vicky's story. Her desire to climb came from childhood walks and holidays in Argyll but it wasn't until she was in her thirties that she began tackling the Munros. Having climbed them all, she set her sights on the Seven Summits. She's fallen off Mount McKinley in Alaska, she nearly died in a blizzard in Antarctica, she was chased by armed security men in Indonesia and, in the face of atrocious weather conditions, had to abandon her first attempt on Everest. Despite all this, Vicky wouldn't call herself a mountaineer - she would say she is just a hillwalker.And, during her years of climbing all over the world, Vicky has also successfully pursued a high-level career. This book is the story of an ordinary woman who pushed herself to extraordinary heights.
