The Suits Undone Books in Order

The Suits Undone series is Mia Sosa's early contemporary romance trilogy, built around ambitious women, powerful men, and the trouble that starts when attraction collides with work. The books are connected through the Ramirez sisters and their wider circle, but each novel gives a new couple its own complete romance.

The first book, Unbuttoning the CEO, introduces Graciela Ramirez and Ethan Hill. Ethan runs a major tech company and is used to being in charge, until reckless driving lands him in community service. He keeps his identity quiet while working under Graciela, his temporary supervisor. Graciela is drawn to him but has practical reasons to keep her heart out of the equation. His secret, their workplace dynamic, and their attempt at a no-strings arrangement make that nearly impossible.

One Night with the CEO follows Graciela's sister, Karen Ramirez, a medical student who has little time or interest in a serious relationship. Then she meets Mark Lansing, a wealthy CEO who will also be the best man at her sister's destination wedding in Puerto Rico. Their plan is to enjoy the trip and return to friendship afterward. The tension comes from the mismatch between Mark's hopes for a settled future and Karen's need to protect her demanding path through medical school.

In Getting Dirty with the CEO, publicist Mimi Pennington is working toward a partnership and needs to land an important account. The potential client is Daniel Vargas, the polished man who previously rejected her. Mimi has no interest in revisiting that history, while Daniel sees a chance to prove that their earlier encounter did not tell the whole story. The professional stakes stay front and center as they test the rules Mimi has set for herself.

Careers do not disappear when the flirting begins.

That is the thread that runs through all three books. Graciela, Karen, and Mimi have responsibilities, goals, and boundaries that matter to them. Their relationships are not presented as an easy escape from work. Instead, the couples have to figure out how honesty, trust, and compromise can fit into already crowded lives. The CEO title in each book signals power and money, but the real conflicts are more personal: fear of being vulnerable, uncertainty about timing, and old assumptions about what a relationship should cost.

Readers can start with Unbuttoning the CEO for the full family connection and a natural introduction to the Ramirez sisters. The series has a warm, steamy, fast-moving tone, with workplace complications, destination-wedding energy, and strong chemistry. It is a good fit for readers who like romances where successful people have to stop treating love like a problem they can solve alone.
