This book tells of Uncle Petros' lifelong search for the proof of Goldbach's Conjecture - "Every even number greater than 2 can be expressed as the sum of two prime numbers". The beauty of the book lies in the author's ability to make this journey thrilling, and even edge-of-the-seat at times.

If I have one complaint, it's that the lives of the real mathematicians that we meet in this book were even more enthralling than presented. The book talks about death, insanity and tragedy in mathematics - a result of "getting too close to the Truth" - but doesn't make the case as strong as it could have.
