A year has passed since the Hamiltons celebrated a holiday as one family. Blake Hamilton—the family patriarch—invited his growing family to a remote Colorado lodge for more reasons than enjoying Christmas. He should’ve known that with his sons and daughter, trouble would find them. The important news he has to share takes a back seat when one problem after another hits them. At ten years old, Reagan Hamilton knows she’ll lead HIS when she’s old enough. In the meantime, she trains with her uncles because she wants to show everyone she will be a good agent. When she arrives at the lodge, a man catches her attention so she decides she has a mystery to solve that involves him. When a crime happens, she sneaks away while dragging her cousins to help their parents find the criminal trying to set up her cousin. When the allegations are proved wrong, but a criminal is on the loose while the weather is working against them, can the Hamiltons protect their family, and the guests relying on them, before events are out of their control?
