This volume by Osprey/New Vanguard gives an overview of British 8 inch gunned cruisers (heavy cruisers by definition) in WW II. Four major sections deal with the design and development of the ships, the specifications of each class, the service history of each ship and a finally a description of the ships' armament and operation, the last part of which actually should have been a separate section as it is a general evaluation of the ships and their effectiveness.
The text is concise and efficiently written, containing a good deal of information in a small space. There are summary charts on the details of each class with one over arching table with comparative information such as dimensions, performance, armament, etc. There are b/w photos illustrating many of the ships but they are almost all of the entire ship from a distance or an angle, so they are not useful for detail.
