It was New Year’s Eve the night that dead blackbirds descended, hours before 14-year-old Alex McCarthy's sister Olivia went missing from a party. Committed to finding out what happened to her sister within the previously safe walls of their subarctic Orkney village, Alex knows that dishevelled, sometimes intoxicated Detective Inspector Birkens is her best shot.

It all starts with a text: "Please, Wylie, I need your help". Wylie hasn't heard from her onetime best friend, Cassie, in over a week. Not since their last fight. But that doesn't matter. Cassie's in trouble, and it's up to Wylie to do what she does best: save her best friend from herself. This time it's different, though - Cassie's texts are increasingly cryptic and scary. And instead of having Wylie come by herself, Jasper shows up saying Cassie asked him to help.
