General relativity: an introduction for physicists, Hobson M P, Efstathiou G P & Lasenby A N (CUP 2005). This covers all parts of the course.
Relativity: special, general and cosmological, Rindler W (OUP 2001). Good for the concepts and methods. Provides a lot of physical and geometrical insight.
Introducing Einstein's Relativity, d'Inverno R (OUP 1992). Provides a clear description covering most of the gravitation course material.
Gravity: an introduction to Einstein’s general relativity, Hartle J B (Addison Wesley 2003). A clear introduction that does not rely too much on tensor methods.
Spacetime and geometry, Carroll S M (Addison Wesley 2004). A very thorough, yet highly readable, introduction to general relativity and the associated mathematics
General theory of relativity, Dirac P A M (yes, that Dirac…!) (Princeton University Press 1996). A short and well-argued account of the mathematical and physical basis of general relativity. Probably only useful once you already understand the subject.
