Lies have kept them apart for eight years.
Now the truth could destroy them completely.
Bomb squad leader Tag Monroe’s world is shattered when his sister and her foster sister are abducted by a human trafficker. Eight years later, the two of them have been miraculously freed. As thrilled as he is to be reunited with his sister, Tag has lingering questions.
How did Jae-won Lin, the third foster sister, elude capture that night? Why didn’t she call the police or Tag to let them know what happened? And where has she been for the last eight years? He loved Jae once, but he can’t let her back into his life until he has more information.
Unfortunately, time is running out. Someone powerful is coming after Jae, bent on revenge. If Tag can’t get to her before her mysterious pursuer, Jae could take the answers to all Tag’s questions to her grave.
Along with any hope the two of them might have to find their way to each other again.
