Amazon has more copies, now? I thought it was sold out...I got mine a month or so ago...
They order in five or ten at a time. It's done through a process called "Print on Demand" which allows them to order however many they think they will sell in a specific time period.
I'm still hoping a big publisher picks it up sometime and puts ten or twelve of them in every Walden's and B. Dalton in the country. Either way ... I'm going to keep on writing.
