The Rarest Blue, is now officially out and available!  attached tekheletbelow some of the reviews  received so far.

We would especially like to share one bit of feedback that was particularly moving to us – by Dr. Kirsten Benkendorff, a biochemist from Southern Cross University in Australia, whose work regarding the murex snail we describe in the book.

A huge congratulations to you and Judy – the book is so well written and engaging that it is really hard to put down! And I learnt a lot – not only about the history – but more surprising to me was how many new insights I got from the chemistry and biology components – it was really so inspiring and of course has triggered a bunch of new ideas and questions…

It is thrilling to us that a book about an ancient color was able to stimulate thoughts of new experiments and research ideas. Tekhelet is a topic that is meaningful, beautiful, and fascinating, offering something unique to each person who delves in to it. We think The Rarest Blue would make the perfect Hanukkah gift, and it is our hope that the book can play a part in inspiring more people in a whole range of different directions.

If anyone knows of any publications venues that might be interested in reviewing the book, please let us know, and if you’ve read the book, please take a moment to review it on Amazon.

Wishing you a happy Hanukkah,

Baruch and Judy
