My name is Macy Kowalski. I'm a registered nurse, a pharmaceutical scientist, a founding member of the Detroit Police Department's barely-legal Shadow Squad, and a walking case study in 21st century man problems. I like things calm and orderly. I have a soft spot for people, so I spend my days developing a formula to help cancer patients escape their suffering. My research has caught the eye of some dangerous members of the self-medicating community, and now I have to make sure my plans aren't polluted by unsavory people who'd rather destroy me, my friends, and my city.By night I have a part-time partner and full-time guardian, Detective Jonas Rafe, fellow member of the Shadow Squad. He is as volatile and unpredictable as anything I've ever dealt with in a lab. I'm smart enough to protect myself when handling chemicals, but I'm still learning when it comes to him.He's sweet when his mouth is closed, but there's no way to prepare for when it opens. In time, his actions speak louder than his words, and though I vowed to never put my trust in another cop, he makes me want to take chances.He's the law, and he wants to protect me. They all do. But I'm neither as fragile nor as pure as he wants me to be. I'm a nerd with a gun fetish. I'm tired of observing, and it's time for me to be in on the action. When he finds out what I've been up to in Detroit after dark, our relationship is tested, loyalties are divided, and lives are put in jeopardy.When our team is under fire, Jonas will finally see the real me. When he does, will he see what he wants to see, or will he be the one who finally breaks me?My name is Macy Kowalski. I am a brawler.
