Book Three of the JACOB'S LADDER sequence.
At last the generation ship JACOB'S LADDER has arrived at its destination: the planet they have come to call Grail. But this habitable jewel just happens to be populated already: by humans who call their home Fortune. And they are wary of sharing Fortune - especially people who have genetically engineered themselves to such an extent that it is a matter of debate whether they are even human anymore. To make matters worse, a shocking murder aboard the JACOB'S LADDER has alerted Captain Perceval and the Angel Nova that formidable enemies remain hidden somewhere among the new crew.
On Grail - or Fortune, rather - Premier Danilaw views the approach of the JACOB'S LADDER with dread. Behind the diplomatic niceties of first-contact protocol, he knows that the deadly game being played is likely to erupt into full-blown war - even civil war. For as he strives to chard a peaceful and prosperous path forward for his people, internal threats emerge to take control by any means necessary.
