Theoretical physicist James W. York wrote that General Relativity is a sophisticated yet concise book on the subject that should be appealing to the mathematically inclined, as a high level of rigor is maintained throughout the book. However, he believed the material on linearized gravity is too short, and recommended Gravitation by Charles Misner, Kip Thorne, and John Archibald Wheeler, and Gravitation and Cosmology by Steven Weinberg as supplements.
