My choices are fairly predictable for this.
- Track of the Cat by Nevada Barr
- The Man of Property by John Galsworthy
- The Light of Day by Eric Ambler
- The Guns of Navarone by Alistair MacLean
- Whose Body? (Lord Peter Wimsey #1) by Dorothy L. Sayers
- Breakup (Kate Shugak #7) by Dana Stabenow
Two those are free (well, in Canada, Australia and Life+50 countries, at least). Two are rip-roaring thrillers, three are mysteries, and one is, at least in part, really funny. All but one I've actually read before, and that one I've started at least twice. But I'm determined to finish it, this time with the help of a good Audible version.
ETA: And yes, I'll be reading whatever wins, and joining the discussion after.
