Not to give away too much about the Daria Gibron thrillers, but I spent parts of 2012 traveling to six countries to conduct research.
All six are in central, southern or eastern Europe. Only one is in the Euro-Zone. Five of the six became independent countries in the 20th century.
The first of the two novels, ICE COLD KILL, is available for pre-order from Barnes and Noble! Very exciting.
The novel hits a bookstore near you in late March: about 90 days out from now!
