This book is a good read regarding a topic in topology. It is accessible to the average reader, and interestingly enough, the conjecture (now a theorem) can be introduced with basic notions of topology but the work involved to prove it far exceeds the statement as it can be shown in the book. I would recommend this book to anyone interested in knowing what is the characterization of a sphere. I.e. What makes a sphere a sphere?
