Harbinger by Kris Michaels

Whatever it takes. As long as it takes.

Alone.
Harbinger extinguished any thought of a serious relationship due to the dangers of his profession. Yet he’d fallen hard for Ysabel Archambeau, and she rejected him without reason. He tried to escape the haunting memories of Ysabel by returning to the States, but the romantic connections surrounding him isolated Harbinger from his team.
Running out of time.
A desperate plea from Ysabel’s family pulls him back into her world and his memories. The woman who had shattered his heart and cut off all contact has become the central pawn in a high-stakes game of old money, greed, and blackmail.
Her Guardian is the only hope.
Sometimes, trust is the deadliest of weapons. Navigating the maze of deceit, love, and vengeance, from the opulent penthouses of Paris to the dark underbelly of the European elite, Harbinger must confront his past, face one of his deadliest adversaries, and unearth secrets that could either reunite him with Ysabel or shatter any chance of a future with the woman he loves.
