Mother, wife, federal agent... mortal. Samantha Moon hadn't always been a vampire. Once, she had been a wife and mother, happily married to her soul mate and raising two adorable kids. Once, she had been a federal agent investigating a world teeming with sophisticated scams, drugs, human trafficking and violence. She had hippie parents and a caring sister. She had a small home with an irritatingly detached garage. She had friends, colleagues and normalcy. That is, until she caught the eye of something evil... But first, she has a job to do. When her HUD team of federal agents is sent in as backup on a drug raid, she spots a mysterious business card on the fridge. Later, she finds the same card during a routine inspection. Convinced the narcotics traffickers are more widespread than initially thought and are taking advantage of those in need, Sam can't let it go – even after the gang tries to send her a message written in lead. Yes, her days at the Department of Housing and Urban Development are typically boring, her worst fear, a paper cut, but little does she know that she has attracted the attention of something dark and hungry. Something that's about to steal her mortal life... and change her forever.

Coping with being attacked and left for dead isn't easy, but Samantha Moon is grateful that she survived ― until she suspects she didn't. Vanishing from mirrors is only the first of a series of bizarre events that defies explanation, even to her trained investigative mind. A severe allergy to the sun, alertness at night, inability to eat food that isn't blood, and worst of all: she can't remember the last time she needed the bathroom. Of course, it's not all bad. Years have fallen off her face, her hair is perfect, her senses are honed, and (assuming she hasn't gone crazy) she can even see in the dark. It's all too much to process, so she does the only thing that makes any sense: tries to go back to work. A huge hat, shades, and half a bottle of high-test sunscreen later, she's back out inspecting properties with her partner Chad. Her first day, she suspects a HUD recipient of having undeclared income. Determined to cling to the career she worked so hard for, Sam traces the money back to small-time arms dealers selling big-time weapons. Everything seems to be routine until her sluggish reflexes get someone shot ― and her husband suffers an emotional breakdown. Worse, she faces a more insidious and dangerous enemy than an apocalyptic militia group with military hardware... Daytime.
