All books of the Iron Druid Chronicles and the Seven Kennings can be found in all the usual places, online and in stores. I do have some links on the individual novel pages for you; just click on a cover to learn more about any of them!
To order SIGNED COPIES of the books:
Please visit The Tinker's Packs to get signed copies of my books. They will ship anywhere in the world and your money goes to the Worldbuilders charity, which distributes funds to Heifer International as well as various refugee and disaster relief agencies. So yeah. You get a signed book and hungry folks get to eat. Great deal, eh?
