Temptation (Ruth Cardello) Books in Order

The Temptation books are a hotter, more self-contained corner of Ruth Cardello's catalog. At the center is one couple, Kate and Brock, and the series works by stretching their attraction, trust issues, and private games across linked holiday novellas.

A Santa letter, a secret fantasy, and a man who takes the challenge very seriously set the whole thing in motion. From there the books lean into seduction, revenge, and the uncomfortable discovery that what starts as a game is landing somewhere much more real. Compared with Cardello's big family worlds, these are tighter and more couple-focused.

They are also spicier.

If you want her voice without a huge cast list, this series is easy to pick up. Later, Untouchable Kate revisits and reimagines this story space in a fuller form, so the page is especially useful for readers who want to see how the earlier setup fits into the broader evolution of that romance.
