Prador Moon

"The Polity, a space-faring civilization ruled mostly by AIs because only they can cope with the math for the runcible operation enabling interstellar travel, has just made first contact. No one knew quite what to expect of the crablike Prador's visit to Avalon Station, though the massacre that ensued wasn't on anybody's list. Seems the bloodthirsty Prador are bent on taking over the Polity and its runcible technology."@en
"Neal Asher takes on first contact, Polity style. This original novel recounts the first contact between the aggressive Prador aliens, and the Polity Collective as it is forced to retool its society to a war footing. The overwhelming brute force of the Prador dreadnaughts causes several worlds and space stations to be overrun. Prador Moon follows the initial Polity defeats, to the first draws, and culminates in what might be the first Polity victory, told from the point of view of two unlikely heroes. For the first time in the US in eBook format."@en
