Query: A good book, but, sadly, a bit too "popular"

There is no question that the author is a genius; what else might one reasonably call a person who has broken two previously undeciphered scripts, in unknown languages?This book is a very popularized account of what was done. Hopefully, it will stir a few people to become interested in the subject. While I'm happy to have the insights into the author's personal travails and triumphs, I could wish that there had been a bit more technical information in the book.
