Into the Abyss charts the dramatic highs and lows of Rod Macdonald's diving career; one that has been packed full of incident, drama, and excitement and has taken him to all of the great shipwreck sites of the world. From the sunken Japanese Fleet at the bottom of Truk Lagoon and Palau in the Pacific to diving into the third largest whirlpool in the world—the Corryvwrecken Whirlpool off the west coast of Scotland—Macdonald's work has taken him on a spell-binding journey beneath the seas, one that is now remarkably chronicled in this enthralling collection of diving experiences. Along the way, the excitement, the successes, and the near tragic failures are reflected upon, and Macdonald urges readers to overcome some of man's deepest fears as he takes them on a journey deep into the abyss in search of long lost shipwrecks around the world.
