For centuries, dyed fabrics ranked among the most expensive objects of the ancient Mediterranean world, fetching up to 20 times their weight in gold. Huge fortunes were made from and lost to them, and battles were fought over control of the industry. The few who knew the dyes’ complex secrets carefully guarded the valuable knowledge. The Rarest Blue tells the amazing story of tekhelet, or hyacinth blue, the elusive sky-blue dye mentioned 50 times in the Hebrew Bible. The Minoans discovered it; the Phoenicians stole the technique; Cleopatra adored it; and Jews—obeying a Biblical commandment to affix a single thread of the radiant color to the corner of their garments—risked their lives for it. But with the fall of the Roman Empire, the technique was lost to the ages. Then, in the nineteenth century, a marine biologist saw a fisherman smearing his shirt with snail guts, marveling as the yellow stains turned sky blue. But what was the secret? At the same time, a Hasidic master obsessed with reviving the ancient tradition posited that the source wasn’t a snail at all but a squid. Bitter fighting ensued until another rabbi discovered that one of them was wrong—but had an unscrupulous chemist deliberately deceived him? Baruch Sterman brilliantly recounts the complete, amazing story of this sacred dye that changed the color of history.

"In 1979 the black robin of the Chatham Islands was on the brink of extinction, with only five birds left. When the Wildlife Service intervened to rescue them in 1980, there was only one female who could lay fertile eggs. She became known as Old Blue. Today there are 200 or more living black robins - all of them her descendants"--Publisher information.

What is it about the color blue? Blue is our favorite color globally—the darling of artists since the time of the pharaohs. So it’s startling to turn to the realms of nature and discover that “true” blue is truly rare. The sea and sky are blue, but we can’t bottle this trick of physics. And the few creatures, plants, and minerals that appear blue are almost all deceiving us. There’s no blue pigment in a blue jay—it would be brown but for how its feathers distort light. Kai Kupferschmidt has been enraptured by blue since childhood. In Blue, he invites readers on his globe-trotting quest to understand his favorite color— from Kyoto, where scientists are trying to engineer a blue rose, to Brandenburg, where conservationists hope to save the “little blue macaw.” Deep underground where blue crystals grow and miles overhead where astronauts gaze at our “blue marble” planet-wherever he finds this alluring color, it has a story to tell.

Spring, 1990. After years of searching in vain, a stranger passes a scrap of paper to Zina. It’s from Aziz: the man who vanished the day after their wedding almost two decades ago. It propels Zina on a final quest for a secret desert jail in southern Morocco, where her husband crouches in despair, dreaming of his former life. Youssef Fadel pays powerful testament to a terrible period in Morocco’s history, known as ‘the Years of Cinders and Lead,’ and masterfully evokes the suffering inflicted on those who supported the failed coup against King Hassan II in 1972.
