In this gripping prequel to his Edgar Award finalist and New York Times bestseller The Deep, Deep Snow, Brian Freeman takes us on Rebecca's dark journey to reveal the truth about the Ursulina ... a journey that ultimately leads to an excruciating choice that will change her life forever.

The mythical beast goes by many names. Bigfoot. Sasquatch. Yeti.

In Black Wolf County, he's called ... the Ursulina.

But to Deputy Rebecca Colder, the beast is no myth. A serial killer has taken on the identity of the monster—and with each body left behind, there's a chilling message written in blood: I am the Ursulina.
