The story is a kind of loose collection of conversations, beginning with Jacques starting to tell his Master. They are endlessly interrupted by a host of other characters with stories of their own and various misadventures on the road. If that weren't enough, the text is laden with authorial intrusions "Where are they going? I don't know! Who cares?" "Ok reader, you're bored with this conversation? Then allow me relate a little anecdote of my own".
In some ways, the novel is an early prototype for choose your own adventure fiction - except in this case, the novel progresses with the choice you have seemingly made. When the characters momentarily part ways, there's a moment there's a moment of debate over which one to follow, and then one is dismissed as too boring and off you do.
It's an interesting book, playing as it does with its fictional status (going back and forth between the author saying he doesn't know what happened and, for example, threatening to send the carriage into the ditch just to create a commotion). It's also a nice take on the stories-within-stories and digression mode, much more effective than Sterne's, I think.
For all it's dry wit and snarkiness though, it's also quite warm and lovable. Really, just a lot of fun to read. Worth checking out.
