The contest is closed. Congratulations Janett Gomez!
I recently changed my profile picture of Facebook: https://www.facebook.com/author.irishwinters
It depicts a young man in uniform behind marble columns (see below).
The first person who can tell me where the picture was taken will win an author signed copy of Connor, Book #5, In the Company of Snipers, as soon as it it released (early November).
