Thanks for making a great carnival. I also wanted to say that the Barnes&Noble near my school had your book… And they don’t have a huge math section, so I was glad they had yours. I loved flipping through it, and I almost bought it, but I didn’t have enough cash on hand. Sigh. But I just want to say: I cannot wait to get it and read it this summer.

Sam.

Cool, thanks for letting me know! I’ve gotten email messages from friends in all around the country saying they found it in their stores—it is great to hear. (Even one from my freshman-year roommate from college!) Wouldn’t you know that our local Borders and Barnes & Nobel don’t carry it! The local independent bookstore has signed copies for sale though :-)

Thanks for the message. I hope you get a chance to read the book, and I hope you enjoy it. I loved writing it.
