The book The Floating Egg begins with the quest for an alchemical secret and ends with the reimagining of a past world. Each chapter is linked to a specific corner of northeastern England and explores the blurred line where myth dissolves into science and belief gives way to knowledge. The various episodic narratives show how the fall of Constantinople transformed common rock from the cliffs of Yorkshire into a source of extraordinary wealth and power, and how this revealed the inhabitants of a series of past worlds. We learn about the world of fossil trade in Whitby and follow the life of a forgotten scientific genius who died of tuberculosis at the age of twenty-five, having revolutionized his science. The stories range from documentary narratives to fictional representations of historical events, combining contemporary writing and illustrations with modern thoughts. Through the use of different ways of describing the world of scientific exploration, the author has created a fascinating, visually impressive, and highly entertaining book that allows us to witness the birth of a new science - the science of geology.
