The saints of salvation
(Book)

"Humanity is struggling to hold out against a hostile takeover by an alien race that claims to be on a religious mission to bring all sentient life to its God at the End of Time. But while things may look grim in the immediate aftermath of the attack, mankind is busy playing an even longer game than the aliens may have expected. Will a strategy millennia in the making finally be enough to defeat this seemingly unstoppable enemy? And what secrets are the aliens truly hiding in their most deeply protected stronghold?"--Publisher.
