1. Booksellers Everywhere
Richelle's books are available from major American book retailers like Amazon and Barnes and Noble, as well as all sorts of wonderful independent bookstores. You can buy online or in person. "Superstores" like Target and Walmart also often carry her books. Most UK and Australian bookstores (like Waterstones and Dymocks) also can get them. Other countries vary.
2. Buy Your Books SIGNED!
Richelle has worked with University Book Store in Seattle to sell autographed copies of her books for a number of years. As of January 20, 2014, Richelle will be on hiatus from signing mail order books for them. This is because Richelle recently had another baby and cannot currently get to the store often enough to keep up with orders. She will likely resume this system in spring 2014. Info will be posted here when the system is back up and running!
