Which one of these books on General Relativity would you recommend?

[Astroman]

Which one of these books on General Relativity would you recommend for an introductory text. I have a background of BS in Physics.

Groen, Hervik. Einstein's General Theory of Relativity

Hobson. General Relativity: An Introduction for Physicists

McGlinn, W.D. Introduction to Relativity

[Daverz]

Is that what's in the local library, or do you get a special deal on those? I haven't seen any of those. I'd recommend Hartle, Gravity.
