Guard your heart - Trust no one
Until his last mission, British military medic Luke McLaren kept his oath, 'Do No Harm.' When he fails to save his best friend, Mike, Luke's life implodes.
Mike's sister, midwife Kate Gibson, doesn't believe in happy endings not since her father deserted her when she was a child, and her brother got killed on a mission.
One night of make-me-forget sex and Luke knows Kate is the only woman he will ever want but can never have. Life goes on. He joins Sentinel Security, and Kate focuses on her clinical work in Africa.
When Kate asks for Luke's help to expose a bomb threat, he agrees. He has no choice thanks to his deathbed promise to protect her. With their hotter than hell connection reignited, Luke and Kate must face their demons and the enemy if they are to survive and claim a future together.
