Query: A must-have for the serious student of Pynchon!

WOW! Never before has so much intellectual horsepower been applied towards the study of the works of Thomas Pynchon. Without doubt this volume should be a given in the library of anyone who wishes to learn anything about the subject, and is a must for those purporting to know everything. Alan Brownlie provides thoughtful and comprehensive insight into issues not typically addressed, even as he shines new light onto topics usually glossed over by others. Don't ask why - just buy this book for your library. There's NOTHING else like it on the market!
