Frequent Traveler is a high-stakes espionage thriller set against the shifting landscapes of modern Europe. Luisa Brightmann, a covert operative for the U.S. Department of Defense, is a master of blending in-her life a constant cycle of train stations, anonymous hotel rooms, and coded messages. When a routine mission in Belgium unravels into a deadly web of international intrigue, Luisa finds herself at the center of a conspiracy that threatens the stability of the entire continent. Tasked with intercepting intelligence about a planned terrorist attack on the upcoming G20 Summit in Marseille, Luisa's journey takes her from the bustling concourses of Liège and Brussels to the shadowy backstreets of Berlin, Paris, and Florence. As she navigates a labyrinth of double agents, shifting allegiances, and brutal betrayals, Luisa uncovers two chilling plots-"Real Madrid" and "Barcelona"- followed by a third, "El Clásico", each designed to ignite chaos and reshape global power. The deeper she digs, the more she realizes that the true enemy may be within her own ranks. With time running out, Luisa must outwit rival agencies, survive assassination attempts, and confront the legendary Black Square Unit-a division renowned for its ability to unravel the world's most complex intelligence cases. As the summit approaches, the lines between friend and foe blur, and Luisa is forced to question everything she knows about loyalty, duty, and survival. The novel's relentless pace and atmospheric detail immerse readers in a world where every shadow hides a threat, and every ally could be a traitor. The hard-hitting conclusion leaves Luisa-and the reader-on the edge of disaster, as the consequences of espionage ripple across nations. Frequent Traveler is a gripping, realistic portrait of the modern spy, perfect for fans of John le Carré, Olen Steinhauer, and Daniel Silva.
