Trigger warnings all over the place but not as bad as you'd expect. Warnings for mentions of torture, r*pe, threats of both, gore, human trafficking, and just threats in general. Most of the kill scenes are fade to black, the mentions are just that, because while r*pe is mentioned it's not something that happened to her or during the book. She goes after those who have been accused but got away with it. So, like I said, no Lt as bad as you'd think for it being a darker book.
Halle/Rainbow had a score to settle with men who've hurt others and not seen justice served. So, she and her knives ensure that justice...of a sort...happens. Oddly, the police aren't thanking her. But she has attracted the attention of a crime family. Seems the son was a bad boy and when he hired her to kill someone she decided he deserved it more. And that's how this very stunning killer walked in on her kill scene and dubbed her Rainbow. He also decided to keep her. Well, he'll see how well that works out when the knives turn on him.
Spoilers ahead.
This was oddly charming while a bit macabre. Two killers dancing around each other, as both are emotionally stunted. We learn only the basics about each of them. He was manipulated by his family to be an enforcer and a measure to keep others in line. She was in foster care/state homes. We don't know how she landed there other than apparently she had no family, or any that claimed her, or was allowed to claim her. It's all very vague. The world building used only sets up the fact that they exist and their careers. The plot is a simple: he's supposed to kill her but can't. The characters do develop- in their own ways. This is not a cuddly romance. The only thing cuddled is her bearded dragon, Richard. But this was darkly humorous. Their ideas of "dates" would send most people screaming. And his presents to her usually involve a cleaning crew and body disposal. But it works for them.
