Actually, this is my favourite way to find new authors.

As an example, R.C. Bray narrated The Martian by Andy Weir, and I loved his narration so much I looked for other books that Bray had narrated. One such book was Planetside by Michael Mammay, which was Mammay's first and only book at the time. I have since read all 5 of his books, and he's now one of my favourite authors.
