This little volume is part of Pomegranate's "Frank Lloyd Wright at a Glance" series, though my copy only mentions that on the inside back flap of the paper cover. It lists no other parts of the series, nor really discusses the intent of the series.
So, be aware that this is a brief introduction, with lovely photographs as representations of his work in glass. The pictures are mostly impressive, and so is the architecture, of course. The brief comments often refer you to other works by Wright, so you can chase them in other books.
There were, in the brief notes, some instances of what I call "word blather" or "art blather." A phrase like, "Throughout, Wright masterfully manipulated the material in countless ways, seeking to capitalize on its unique nature" is accurate, but it's also just noise.
As a lover of Wright's work this was a great piece of literature to read, it gave me a better understanding of his architectural style beyond just the visual elements. Wright does a great job of researching the surroundings of the property before beginning the job. He incorporates color, sound, lines of environment, and even the landscape itself into his works, making him a modernist even by today's standards.
