Okay, I feel like I have to shout out 'Uncivilized' first because that's the one that hooked me. It's not her most recent, but that whole 'Sawyer effect' of taking a character who's completely isolated from modern society and throwing them into the corporate world is just so perfectly executed there. You get the culture clash, the slow-burn tension, the whole 'fish out of water' thing that she writes so well. I started there on a whim after a friend's recommendation and then basically mainlined her entire backlist.
If that darker, more intense vibe isn't your entry point, the 'Sugar Bowl' series is probably her most commercially explosive work for a reason. It's a trilogy, so it's a bigger commitment, but the premise is utterly addictive—it's this revenge plot wrapped in a high-stakes mystery, and the pacing just doesn't let up. A lot of readers found her through those books, and they definitely showcase her ability to weave a complex, plot-driven story with seriously steamy romance. Her 'Arizona Vengeance' hockey series is also a massive seller and a super safe, fun starting place if you want something more in the sports romance lane.
Honestly, her bestsellers are usually her series starters, so you can't go wrong picking the premise that appeals most.
