Edith has always been a good girl--she has to be, or her foster family might think she's like her violent father. No matter how much anger simmers inside her, she keeps it buried, hidden...

Until the day she's pushed a step too far, and that anger comes bursting out in the form of literal claws.

It's then that Edith learns she's a berserkr, a descendant of ancient Norse warriors with the ability to turn into animals. To avoid jail for attacking a student, Edith is shipped off to the mysterious Skallagrim Academy. The ancient school is supposedly a haven for people like her, a place where she can learn to control her powers and then push them down so deep that they'll never come out again.

But someone--or something--is stalking the dark halls of Skallagrim.

On her first night, Edith stumbles upon a gruesome murder and is caught at the scene of the crime by Amund, who is tasked with hunting down wayward berserkir. Now, with Amund suspecting Edith as the killer, she'll have to catch the real culprit to prove her innocence before she ends up in the hunter's crosshairs--or becomes the killer's next victim.
