I think she's a great author because of her stories, not, because of her philosophical beliefs. While those were interesting to read. Keep in mind, I did read more than just Atlas Shrugged. The Fountainhead was good as well, in fact probably more so. Mostly because I found the setting much more appealing. But eh. I use the term great because she captivated my interest enough for me to read books that would take normal people weeks, in a few days. That and her characters were quite unique. Or at least unique portrayals of character stereotypes, which made for a more interesting read in all.
