Elite hacker Azi Bello lives his life in the technological underbelly of the 21st century. A loner, charmer, and lover of grey areas, he works for himself and answers to no one - until his online existence crashes violently into the real world. The secretive but intriguing Munira has reached out to Azi for help, and her story has sparked his interest: Munira's cousin has been recruited by terrorists and, in her attempts to find out more, she has attracted the attention of some very dangerous people. Now forced to go on the run, Azi and Munira are drawn into a conspiracy, at the heart of which is Gomorrah: an exclusive online marketplace where anything can be acquired, and where the world's worst individuals lurk.
