House of Steel by Raen Smith
Book #1 in the Unraveled Series. House of Fire (#2) and House of V (#3) now available.
For young art professor Delaney Jones, the unraveling of her tight-stitched life begins when she makes one unforgivable mistake - she sleeps with her student. Her silent Wisconsin winter turns deadly after she witnesses the brutal murder of a man she had chosen to forget, and soon the small liberal arts university is devastated by the discovery of a bloody scene on campus. As Delaney struggles to make sense of the crimes, a mysterious text entangles her in the violent scandal. She must follow the rules of the anonymous messenger to stop the murders, but the line between good and evil is blurry and maybe, just maybe, there is no line at all.
