Query: My favorite book in years!!!!!!

I was so impressed with this book that I went out and immediately bought twelve copies and shipped them to friends all over the country so they could share the experience with me.The history of philosophy interspersed throughout this book is amazingly accessible and thoroughly readable. The plot within a plot within a plot engages the reader from the very first page driving you on to find out what will happen next to the incredible cast of characters.My only regret is that I will never be able to have the experience of reading this book for the first time again
