In war-torn Europe of 1872, Karol and Hart devoted themselves to protecting England and the peace England maintained. Hart was a spy and bodyguard for Karol, a brilliant but hotheaded scientist. Their partnership was almost unstoppable... until Hart could no longer bear to see Karol in danger—or with other men—and seeing Hart repeatedly put his life on the line came to terrify Karol. Then a horrible accident separated them for what they believed would be forever.
Now the enemy's plan to kidnap Karol has Hart volunteering to guard him once again. Alone together with their fear and pain from the past might destroy them... or it might give them hope for a brighter future.
