What dark secrets does the girl in the ice hold? As Erika gets closer to the truth, the killer draws nearer. The last investigation Erika led went wrong and resulted in her husband's death. With her career hanging by a thread, Erika must now battle her own personal demons and a killer who is deadlier than ever before.
