Cass Sunstein & Adrian Vermeule are THE Constitutional and Administrative Law scholars (both professors at Harvard Law). This book is an incredible defense of the administrative state, building on both the authors' separate works defending Chevron.

This work traces trends in the Roberts' Court administrative law jurisprudence to explain why Chevron isn't going anywhere. The Roberts Court will continue to offer "guard rails" for the doctrine but will not overrule it entirely. (And, Sunstein & Vermeule have been proven right! Just look at West Virginia.) This is an invaluable work for all those studying administrative law today.

(The reviews here on GR make me sad. This is a book for law professors and other academics. It's not "dense" and "unreadable," it's... literally published by Harvard University Press.)
