Andrej Nikolaidis was born in Sarajevo in 1974. Accordingly Wikipedia calls him a Bosnian author. However,his father was a Montenegrin from Ulcinj and the family moved there when the war broke out after the break-up of Yugoslavia. The three books of his translated into English are all set in Montenegro, so I have called him Montenegrin.
Nikolaidis became very active in politics, supporting Montenegrin independence and human rights. He was active in both print and TV journalism and, as a result of his views, received death threats. He has been involved in various political feuds, particularly with the actor Emir Kusturica. Three of his novels are available in English.

Note Nikolaidis does have a Twitter account but at the time of writing he has never used it.
