The Death Angel

After a career-destroying mistake in Boston, Cassidy Henderson is transferred to Greystone, a cold and silent town where nothing seems to truly happen.

Until the first body turns up.

An influential businessman is found dead in a locked office, his throat slashed and strange wings drawn in blood on the wall. The police treat it as a common homicide.
Cassidy knows it isn't.

As she tries to uncover who is behind the murders that are beginning to spread through the city, she realizes that someone is always one step ahead of her.

Watching.
Manipulating clues.
Waiting.

Known only as Shadow, the killer seems to transform each crime scene into a personal message directed at her. And the closer Cassidy gets to the truth, the more she realizes that Greystone hides something far worse than corruption or violence.

Because in this town, monsters don't live in hiding.

They make the rules.

And one of them seems to have chosen Cassidy as their next target.
Cassidy is given the mission to find him.

The case, however, doesn't end where it should.
