I was wondering if someone would be willing to suggest an alternative reference to Davenport's book Analytic Methods for Diophantine Equations and Diophantine Equations. I like the book but I would like to read up from a different source some theorems about the geometry of numbers which are important to analytic number theorists. I apologize if the question is too broad. Thanks! 



Alternative reference to Davenport's Analytic Methods for geometry of numbers?
Some classical books on the subject, I use them all:


* Cassels: An introduction to the geometry of numbers
* Gruber-Lekkerkerker: Geometry of numbers
* Siegel-Chandrasekharan: Lectures on the geometry of numbers
