This concise volume is at once an introduction to "Kant's Critique of Pure Reason" and an analysis of Kant's ideas. Intended to be read in conjunction with Kant's text, Ewing's commentary systematically examines the Critique chapter by chapter. It offers guidance to new students of Kant and discussion to advanced scholars.
This book does a good job of explaining Kant's thought process, but it can still be as intimidating and wordy as reading Kant himself. If read concurrently, I think it would help the reader get through the Critique of Pure Reason.
