Artificial Evil — Colin F. Barnes

Humans are no longer the biggest threat to survival.

In a post-apocalyptic future, humanity survives within a single domed city ruled by a shadowy organisation known as The Family. Gerry Cardle reluctantly runs the Death Lottery. It's a job he despises, yet one which keeps his name off the list. Until one day, despite his agreement with The Family, his name is inexplicably drawn next.

With his world crashing down around him and with just seven days left to live, Gerry realises that the system has been breached by a malicious artificial intelligence. In order to save his life and preserve the safety of those within the city, he must do the unthinkable: flee to the abandoned wastelands outside the dome. 

Bitter, resolute, and with nothing left to lose, Gerry will have to do whatever it takes to survive--even if it means sacrificing his freedom, and possibly worse--his life.
