For those who love this SciFi trilogy, this provides game rules for the Double Spiral War. Note that this is not your typical Traveller universe, the ships don't use jump drive and the empires in conflict each cover half of a small galaxy. If you are looking for Third Imperium material, this won't really work. On the other hand, it has have some great ideas for a referee to borrow from for any sci fi campaign and is also great for creating a Traveller universe that uses different technology than the typical one.
Variant rules in the book include alternative startship construction drives so the referee can create FTL ships more akin to those in the novel (though the Hunter/Killers using these rules are not as limited as those in the novels.) Character career paths and world descriptions are included.
Overall this is a very complete book, just lacking the Mongoose Traveller core rules in order to play a detailed, galaxy spanning campaign.
[5 of 5 Stars!]
