surely an audio book collection of files is like a collection of songs in an album. Equate album to a-book & use any media player / organiser, even microsoft's own free windows media player. - I don't see what functionality is lacking, except for some of the metadata nice-to-haves,
the equivalences are
author = artist
book = album
song = track
book cover = album cover art
metadata fields exist for genre, year, rating .... & lots more microsoft defined stuff that I never use but which could be adapted to suit e.g. read by = album artist
put the books in your music folder in windows using author / book title subfolders, then you have individual tracks in the loweest level folder. you can add cover art as folder.jpg to each folder if you so wish. then use playlists for playback . QED.
if you don't care for WMP there are lots of free alternative players which will organise & playback mp3 files , which is all an audio book is. ( & if you are an apple fan then itunes already does all you want, including send to portable device, retrieve metadata....)
