The first in an exciting new series from the author of SILENCE OF THE SEA, winner of the 2015 Petrona Award for best Scandinavian Crime Novel. The only witness to a shocking murder is the victim's 10-year-old daughter, Margret. The police turn to the Children's House for their expertise in childhood trauma. Freyja doesn't much like the police - especially the detective in charge, Huldar. But she does want to help them catch the killer. And when more people die - their murders heralded by strange messages, texts, and strings of numbers - only working together will prevent danger getting ever closer to home.
