Well, probably 90% of my books come from estate sales, library sales, used bookstores, and little free libraries.
But....
Okay here's where you can get those books:
Bone Palace on Amazon
I see a copy of Bone Palace on eBay, too, but that's less likely to remain a useful link long-term so that one I'm not creating....
Thriftbooks.com also has a copy
Actually all those titles can be found on ebay, Amazon, or in Thriftbooks.
so you can go online for them there, or try your local library, or try your local bookstore.
