Titans Books in Order

The Titans books take Sierra Cartwright's billionaire romance instincts and push them into a bigger, glossier world. At the center is a secret society made up of powerful, ambitious men, the kind who can shape businesses, crush competition, and still end up blindsided by the right woman. If you like money, influence, private clubs, and heroes who are almost too used to being obeyed, this is the lane.

What makes the main Titans line work is that the books are connected more by world than by one tight plot. Sexiest Billionaire throws Jaxon Mills into conflict with Willow Henderson after he spots her in a New Orleans club. Billionaire's Matchmaker turns on a practical assignment gone very personal when Hope Malloy is hired to find a wife for hotel heir Rafe Sterling. Billionaire's Christmas continues Rafe and Hope's story. Then the series moves outward with Determined Billionaire, Scandalous Billionaire, Ruthless Billionaire, and later Forbidden Billionaire, each built around a different man in the wider Titans network.

Power is everywhere here.

Sometimes that power is social. Sometimes it is financial. Sometimes it comes from old family expectations or the quiet rules of an elite circle that assumes it can get what it wants. Cartwright gets a lot of tension out of pairing those men with women who are not easily dazzled. Matchmakers, daughters of housekeepers, exhausted maids, and women with their own plans all walk into rooms where the hero expects control and quickly find ways to upset the balance.

The tone shifts from book to book. Some entries feel more like polished contemporary billionaire romance. Others lean harder into kink, legacy pressure, or a darker possessive edge. That variety is part of the appeal. You are staying in the same broad universe, but the emotional flavor changes depending on whose story you pick up.

The shared backdrop also opens into several related subseries, which is why Titans can feel like a hub rather than a single shelf of books. Even so, the main line stands well on its own. You do not need to memorize a whole universe to enjoy it.

Start here if you want Sierra Cartwright at her most society-minded and decadent. These books are about rich men with too much reach, women who matter too much to dismiss, and the messy moment when control turns into obsession.
