I have to admit I am biased, I'm a Traveller player and therefore am predisposed to like this book. The story is quite good and a fantastic idea for playing traveller (or any other sci-fi game for that matter) when you are short of players. All you need is one referee and one core player, new players can be slotted in at any time, for a one shot appearance or occasionally a recurring role.
The story is presented in numerous short periods of activity, separated by extended periods of time (much like game sessions). It's like an ongoing Traveller campaign that was planned for only two regular players and whoever else can be coaxed into playing for any given game session. The two regulars are the referee and one player who plays the main character, most other characters in the story are npcs, a few are pcs when players are available.
Btw.... this is not a game module this is a Traveller novel.
I found it to be a fascinating read, a brilliant idea for game play and an interesting addition to the OTU.
