If an indie book really started to take off, with signs of becoming a mainstream bestseller, could an indie press like BRW “handle” its journey all the way?

Yes!!! One of the main differences between a big five publisher and Black Rose Writing is that we are print-on-demand. However, as technology has continued to improve, our “speed to market” has also become much faster, and there isn’t any reason we can’t fulfill book orders quickly and easily. Your distribution, along with discount terms and returnable terms, are capable of reaching mass markets across the globe.
