The captain might be handsome, but he’s intent on turning her over to some finance lord who has, for reasons unknown, put a bounty on her head, a ridiculously large one at that.

But Ankari Markovich is trouble from the start, nearly eluding his elite forces, then fighting and tricking his people left and right. He finds himself admiring her spirit, but according to her warrant, she’s a criminal. The safest thing is to keep her in the brig and ignore her until she can be handed off to the man who wants her.But the situation grows more complicated when other bounty hunters show up, wanting to claim Ankari for themselves. Thanks to this woman, Viktor’s ship is in danger, his crew members are going missing, and he’s fighting enemies he never asked for in a jungle in the middle of a hurricane.
