Query: Exactly what I wanted, easy to read and understand

This book was exactly what I was looking for. While understanding the GoF Design Patterns is useful, this book goes into sufficient detail to explain them (and online searches for the DP's is easy enough). The book expands into naming the various refactoring so as to have a shared language describing (naming) those refactoring methodologies. Overall I have been pleased with the level of detail and content.
