The famous virtual universe “Mass Effect” has found literary embodiment. For the first time in Russian, a new novel in the series of novelizations is “Retribution”! The criminal group “Cerberus”, led by the mysterious Phantom, as befits the mafia, does not forgive apostates. Paul Grayson, having safely hidden his daughter, hides at Omega Station, infiltrating the organization of Aria T'Loak, the Pirate Queen. Omega, located in the Border Systems, has long served as a haven for adventurers and fugitives from all over the Galaxy, and there is no better place to hide. But the Cerberus agent manages to track down Grayson. Having kidnapped his former employee from Omega, the Illusive Man decides to make him the subject of an experiment that will turn Grayson into a puppet of the Reapers - monstrous intelligent machines coming from the depths of space to destroy humanity.
