When Special Agent Nikki Hunt is called to the Boundary Waters near Stillwater, Minnesota, it’s not just the cold that shocks her to her core: the body of a young woman has been found frozen beside a remote lake. Nikki is devastated to see the victim is her childhood friend Annmarie, and she recognizes the velvet ribbon tied in her hair as the hallmark of a serial killer who she has been hunting for years.
Desperate for justice, Nikki throws herself into the case. But she is shaken by what she finds at Annmarie’s home: a dead-bolt on her front door and a map in the spare room, with the locations of murdered women circled in thick, red marker. Did Annmarie know she was next? Then Nikki finds out that the killer has left a clue in Annmarie’s bedroom: a photo of Nikki’s mother that no one has ever seen. Has the murderer at large been in Nikki’s life since she was a child?
Nikki soon realizes that the key to unlocking this case is in her own family, but digging up the past could put her own daughter in danger. She has spent her whole life protecting the ones she loves, but to find this killer Nikki might have to risk everything…
Review

From the first installment, I knew this would be an awesome series and so far, it has been quite captivating.
FBI Agent Nikki is back. In previous books, we were introduced to Frost in passing. This is a serial killer who Nikki has been hunting for years. He is the unsub in this story.
The story begins with the murder of Nikki’s childhood friend. The posing of the body, killer’s calling card and other clues have Nikki convinced that Frost is near her and is seeking her attention. My curiosity was piqued right from the first chapter. Who is Frost? Why is this unsub fixated on Nikki? I couldn’t guess the answers to these questions.
This was an interesting, twisty case. I enjoyed following the investigation and loved how well Nikki’s team worked together. I love Nikki, Liam and Courtney and have always enjoyed the chemistry between the 3 Investigators. I also like how Caitlin, the once annoying journalist, is now sort of part of the team. This book has so many characters that I have grown to like. Rory and Lacey are my favorites outside the investigating team.
This was an emotional case in many ways and the stakes were higher for Nikki. Needless to say, the tension seeped through the chapters. Frost having eluded the investigators for years was not an easy unsub to catch. I was curious to see if and how Nikki would solve the case. This had me turning pages, captivated by the story up to the end. I can’t wait for the next installment.
Twisty mysteries are the best! Also, I love this cover!
