This is an excellent site for education about all Native Tribes. Their "Resources" page is wonderfully full of real stories. The "Shop" page is really great too. Lots of books sorted by subject the list is huge. We would feel confident about any of the books they recommend.

There's so much to accomplish with a new website that we sometimes feel totally incapable and are worried about all the "Coming soon" messages we're leaving for you.

Lea and Paula
