I've created a list of links for the episodes of our The Earth Will Shake reading group at the top right of this page. My blog entries haven't been any great shakes, but I'm in awe of the quality of the comments posted so far. Please let me know if there's anything else I should be doing to support the group.
We're only going about 20-25 pages at a time, so if anyone wants to jump in and catch up with us, that shouldn't be hard.
