Special Agent Nicole “Nikki” Hunt returns to her hometown Stillwater, Minnesota for the first time in twenty years. The last time she was here was when she discovered her parents’ dead bodies in their home one night and she was the primary witness in the case. She had seen Mark Todd that night and following her testimony, Mark was arrested. This time Nikki was invited to visit a crime scene in Stillwater, where the local police had found the dead bodies of two young girls dumped in the snow. Since she is the expert in the serial killer Frost cases, she was informed, but this is not how Frost behaves; there are several differences. Will she be able to find who killed these girls? Shockingly, new evidence reevals that Mark Todd is innocent. Is this case somehow connected to her parents’ murders?
