About Sinner and Saint Series
Lucy Score’s Sinner and Saint books form a very small series, but they have a sharper identity than their size might suggest. On her official site, they are grouped as the Sinner & Saint novels, and the core line consists of Crossing the Line and Breaking the Rules. There is also official bonus material connecting this world to Blue Moon, which makes it clear that Score sees these books as part of a living shared romance landscape rather than two isolated standalones.
What makes the series work is the central pairing and the kind of world they inhabit. Xavier Saint is all control, discipline, and protection; Waverly Sinner belongs to a life of celebrity, exposure, and carefully managed appearances. That contrast gives the books their emotional engine. These are not small-town comfort romances or broad ensemble family books. They are more tightly focused, more glamorous, and more built around danger pressing directly into the love story. The tension comes from two people who should be able to handle high-stakes situations and yet are far less equipped to handle each other.
Publication order matters because Breaking the Rules is not a disconnected follow-up. It returns to Xavier and Waverly after the events of the first book and builds explicitly on what happened between them before. The official description frames it around the fact that five years have passed since Xavier made the mistake that nearly cost Waverly her life and since he saved her and then left her. That kind of setup only lands properly when the first book has already done its work. This is a two-book arc, not a set of loosely related romances sharing a vibe.
That also means the series reads differently from many of Lucy Score’s better-known lines. Knockemout, Blue Moon, and Bootleg Springs are built around towns and communities that widen over several couples. Sinner and Saint is more concentrated. The focus is less on an expanding cast and more on one emotionally charged relationship shaped by danger, old damage, and the difficulty of rebuilding trust once it has been broken. Because there are only two main books, the series feels tighter, more personal, and more dependent on the chemistry and history of its central couple. This is one of the reasons reading in order pays off so well. The second book is richer when the reader already knows exactly what Xavier and Waverly once meant to each other and why that history still hurts.
There is also a useful tonal distinction here. These books are still unmistakably Lucy Score in their readability and emotional directness, but the mood is more high-pressure and image-conscious than in her more rooted small-town series. Celebrity, protection, public scrutiny, and private fear all matter. Waverly is not simply a glamorous heroine, and Xavier is not simply a stoic protector. The books work because the external world keeps forcing them into conflict with the selves they have tried to construct. That gives the romance a more bruised and urgent feel than a lighter enemies-to-lovers setup would have.
For readers who already have the list above, the best way to think about Sinner and Saint is as a compact two-book contemporary-romance sequence built around one central relationship rather than a broad community series. Read in publication order, the books become more than two connected love stories. They form one concentrated arc about damage, protection, fame, and the hard work of trusting the person who once mattered most and failed you anyway.
