It's so frustrating that some Barnes & Nobles aren't carrying it. 1) I think they underestimate the broad appeal of robotic sports and 2) had previously carried some puffy, photo-driven robot competition books that didn't sell well.
If you find a bookstore in your area doesn't have it, TELL Them they are fools and better order this runaway hit book!
For now though, I suggest you go to
www.booksense.com, a coalition of independent bookstores. Search for Gearheads and then put your zip code in, and it will tell you the closest store that has it. You can also try Amazon.
Good luck in Houston!
