Birthright

Caleb Mitchell is a human weapon, engineered into a biologically enhanced killing machine in the war with the alien Tahni. The war is long over and now he just wants to live a normal life as a constable on his homeworld of Canaan...but his life is torn apart when a Corporate Council mineral scout comes to him with a tale of discovering incredibly advanced alien technology from the fabled race known only as the Predecessors. Someone in the monolithic, power-hungry Corporate Council doesn't want that story to get out...and they'll kill anyone to stop it, including Caleb and his family.
