The world's sub-Antarctic islands are brutally cold, uninhabited, bleak and beautiful outposts circling the lower part of the globe. They sit below New Zealand, Australia, Africa and South America, in the 'Roaring Forties' and 'Furious Fifties' latitudes. They are constantly buffeted by lashing rain and furious gales, surrounded by a deep and roaring ocean. And yet, humans have not been deterred from these islands which are so fully in the grip of nature's power.

From early explorers and sealers to modern-day conservation and adventure tourism, the sub-Antarctic islands have been a common waypoint for those headed to Antarctica, and for scientists discovering the unique plants and wildlife that have earned the islands status as World Heritage sites. Shona Riddell herself is a descendant of 19th-century British settlers who attempted to create a home in this environment. She hopes to shed light on these 'forgotten islands' and their rich human history.

Trial of Strength is filled with compelling photos for a modern audience. Balanced and engaging, it features tales of infamous shipwrecks and lesser-known stories of intrepid pioneers, as well as accounts of modern-day conservation wins and dramatic helicopter rescues, all with women's stories as more than just a footnote. It will leave you with an appreciation for the tenacity of the human race and the forbidding forces of nature.
