Because of a lack of storage space and lack of e-reader I'm stuck on audio, meaning narration is most important - can't abide this new fangled AI generated narration, which lacks all nuance. Author's I currently like a great deal are B.V. Larson, Vaughn Heppner, Ken Lozito, Christopher Nuttall, Four Horsemen Tales (multiple authors) and Craig Alanson - none of this is heavy sci-fi.
