If you know nothing of Farscape...
...then perhaps you'll enjoy this book. I found the concept intriguing, the story mediocre, and the representations of characters, defined and honed in season after season of the series as well as the previous books, abominable. I have no idea who these people were based upon but they were the most overtly simplistic caricatures of Crichton, Aeryn, D'Argo, et al. It has taken me over 3 months to finish this little book because I keep it in my car to read only when I'm going through a drive-thru and have no other escape. I would have put it down long ago but (a) I'm stubborn, (b) I really liked the concept, and (c) I keep hoping it will get better.
The idea of beings, after charting galaxy after galaxy, suddenly being stuck in space for millennia is intriguing and I did enjoy the sub-plot with Sha Sutt and her crew. Perhaps because I knew nothing of these characters I found their bits more interesting than anything else. Frankly, leave out the stock FS characters and this book would have been much better.
As for my expectation of the FS characters and the inept portrayal of their humor, I nearly burned the book when I came to this paragraph:
"There was dead silence from Pilot, then with low and sincere tones, he commanded the former ruler. `Use the furze, Rygel!'"
I might have tolerated this from Crichton, but not from Pilot. Instead, Crichton's dialog was more befitting of a Keanu Reeves impersonation that despite his acting talent, I just couldn't see Ben Browder as Crichton delivering. Therefore I was left wondering who was possessing Crichton's body and thankfully it finally was possessed so at least he didn't have to be the "normal" Crichton.
The list goes on, each character seeming strange and unknown as if it were written beforehand and the character names changed to fit the FS universe. Or maybe my imagination isn't as good as it used to be. Either way, if you love Farscape, don't bother with this book unless you are prepared to ignore things like D'Argo's flat "I am warrior. I will fight. Grrrr..." representation.
