I do enjoy Cal Newports work and his approach. This book builds upon some of his recent essays and podcasts, and is specifically targeted at knowledge workers. It's harder to measure work of this bunch due to it's often intangelibity. He wants through his advice to deal with this by doing fewer things, working at a natural pace, and obsessing over quality.

The book touches each topic and brings some recent and current day examples to the dialog. He hints at a potential series of titles about working in the modern age. Between this, his recent two titles "Digital Minimalism", "A World Without Email" kind of set the stage for a natural progression, all starting from "Deep Work".

It's written in a very readable tone, and might take a focused reader 2-4 hours to read speed depending from cover to cover. If you've read his other books, this is the same form.
