P. R. Davies' slim volume on the Book of Daniel is a helpful resources for students who are interested in Daniel. Davies surveys a number of important themes and topics in Daniel, including the multiple genres of the book, the multiple languages, the theology, apocalyptic viewpoint, etc.
It is almost equal in length to John J. Collins' FOTL work on Daniel, which in my opinion is a better introductory overview of Daniel, although I did appreciate the way in which Davies moved thematically through Daniel, rather than simply chapter by chapter, or section by section. Davies overemphasizes the different viewpoints on Gentile rule in the two halves of Daniel; while the stories may at times seem more cordial to Gentile kings and their kingdoms than do the visions, they are just as critical of empire as the visions are. The dream of the destruction of the four kingdoms in Daniel 2, for example, is the second most critical analysis of Gentile rule in Daniel, following the vision of four kingdoms in Daniel 7.
Unfortunately, the copy of Davies' book that I got from the library also had a number of pages that were left unprinted, so certain chapters I was not able to read in their entirety.
