This is a book review of A Short Course in General Relativity and Cosmology by Reinhard Hentschke. The book is like (and presumably is) a set of well written lecture notes. It concentrates more on the forest than on the trees, but that is not a disadvantage; on the contrary, many broader introductions, especially on cosmology, are available, as are more advanced texts; this book is a useful bridge between the two extremes, especially those more familiar with old-style cosmology (the classical tests to determine the cosmological parameters) who want to learn more about topics such as the cosmic microwave background, structure formation, and inflation. I've often felt the need myself for a book between, on the one hand, popular and introductory-level presentations and, on the other, more advanced textbooks and technical monographs, especially one which covers topics I am less familiar with; I think that this book would serve such a need for others as well.
