Yes, Big Noodle Books has them. I searched and both State of Wilderness and State of Quarries are available. The best part of it is you can sign up with your school and earn money for them. If you purchase certain titles during "book fair weeks," more funds go to the school. I can't think of a better way to have a book fair with very minimal work on the school's part. Everything is online and they boast over 300,000 titles and growing and not all books are for kids. Parents can shop for themselves as well. They have categories like crafts & hobbies, adventure, juvenile fiction, sports & recreation. There are plenty of books to browse through.
If your school isn't aware of this site, check it out and recommend that your school be involved as well. Everyone wins - kids, parents, schools. Hope to see you all there. Thanks to Elizabeth Dulemba for the heads up. Mrs. E :)
UPDATE (04/24/2010): This morning I decided to check out all of 4RV's books on the site and all but about five or so are listed with Big Noodle Books. How cool is that? I'm not sure how to get those that aren't listed there but I may have to contact them and find out so that everyone in the company is represented. (Books not found on the site include Just Breeze, Trockle, Bubba and Giganto, Case of the Missing Coach, The Base Stealers Club and of course Midnight Hours and Confessions of a Former Rock Queen.) It's awesome to have almost every book in the company on this website. Thanks Big Noodle Books for carrying the 4RV books. - E :)
