Lake Of Darkness By Roberts, Adam

Good is a construct. Evil is a virus.
The Starship Sa Niro and the Starship Sß Oubliette were in orbit around a black hole, one afternoon... by the end of the day, the crews of both starships were dead, victims of a single killer: Captain Alpha Raine.
Raine claims he''s acting under the command of a voice emanating from the black hole: Mr Modo. No one believes him.Everyone knows that things go into black holes; nothing comes out.
But something inexplicable has been happening to Raine, and whatever it is seems to be spreading. An historian studying serial killers from the 21st century interviews him... and then nearly kills someone herself. It becomes increasingly undeniable that there''s something inside that black hole... and it''s found a way out...
