Differential geometry reconstructed: a unified systematic framework

[yottzumm]

The first few sections of this book gave me a good sense of the solid foundation that the author is building in this book. While it may be review for many, this guy writes so well, it's a pleasure to read. http://www.scribd.com/doc/18436832/Differential-geometry-reconstructed-a-unified-systematic-framework

I have skimmed this book briefly, it (obviously) seems very comprehensive. I have also heard a friend talk about, so it seems good. Remember that it is a work in progress, so to get the most recent edition, go here:
