"This book is the best Groovy 2.0 title available at present; it's well written and very clear, and should be the first choice for developers interested in Groovy â despite its limitations. For Groovy developers, it's a must-buy update."
--Andrew Binstock, Dr. Dobbs
"If you are not already a Java programmer, you won't need this book; but if you are concerned with adding dynamic productivity this is a good introduction to the concept, as well as a tutorial in the Groovy programming language. It starts off simply (assuming you are already familiar with Java) and continues to some very sophisticated techniques. Java Programmers concerned with looming obsolescence will find this a valuable book.
--Jerry Pournelle, Chaos Manor
