Good Earth Science Books

[darkchild]

I'm looking into purchasing a textbook or two for self-study of planetary science. I don't have any background in the subject, but I have an undergraduate physics background so I would like something that doesn't approach the subject from too low of a level. I'm considering studying planetary science in graduate school and I need to decide if it's something I would enjoy, so breadth is more important than depth.

Any recommendations?

Thanks.
