From the reviews: "Granite Genesis: In-Situ Melting and Crustal Evolution is a timely, well-structured, and enjoyable read. The authors provide a useful introduction to granite terminology and the 'granite debate' ... The book benefits in continuity and style from having only two authors and is easy to read. ... this book provides a valuable synthesis and is a great reference for all graduate students and professionals interested in granitic rocks, from their petrogenesis to emplacement mechanisms."
