Covenant of Ascent: O'Sheerans Books in Order

Covenant of Ascent: O'Sheerans shifts from biker compounds to penthouses and private jets, following the largest Irish mob family in the United States. On the surface, the O'Sheerans are polished businesspeople with a global empire. Beneath that sheen sits a legacy of violence and a fierce code about how family is protected.

The series opens with Darragh's Dilemma, where Ashlynn, desperate to shut down a pornography ring preying on underage girls, goes to the O'Sheerans for help when the legal system fails her. Darragh, heir to the family and head of the business, recognizes her as his soulmate the instant she walks in. Their story introduces readers to a world where wealth, security teams, and private islands sit alongside threats from rival Irish outfits.

In Cian's Complication, the second oldest brother falls for a woman who has been in his orbit for years without him knowing it: the daughter of a man who would happily see the entire O'Sheeran clan behind bars. Later books, such as Aidan's Ardor and Aisling's Craving, explore other siblings who balance personal desire against arranged marriage expectations, business alliances, and the lingering shadow of the family's criminal past.

One of the through lines in Covenant of Ascent is the idea that every O'Sheeran deserves a true love match. Their parents built their marriage on that belief, and their children refuse to give it up, even when outside forces push for political unions. Soulmates are spoken of openly, and once an O'Sheeran decides someone is theirs, they commit with a single minded focus.

The ongoing conflict comes from more than one direction. Law enforcement watches closely, convinced the family's claims of going straight are mostly smoke. Rival organizations test boundaries, looking for weakness. Inside the family, secrets and old choices occasionally resurface, forcing hard conversations about loyalty, justice, and how far they will go to keep women and children safe.

Readers who enjoy mafia romance will find familiar beats: guarded mansions, security details, Italian or Irish dinners, and power meetings in expensive suits. What sets this series apart is how domestic and warm the O'Sheeran household often feels. There are boisterous siblings, protective parents, and a sense that being folded into this clan means gaining an entire village, not just a husband or wife.

Spin off pieces like Patrick's Soulmate and O'Sheeran's Gifted Angels add depth, showing earlier generations and side characters in more detail. Those stories round out the Covenant of Ascent idea, the unspoken agreement that this family will always climb together, even when the route up is bloody.

If you like the mix of luxury and loyalty, high stakes business and private tenderness, the O'Sheerans offer a different but still very recognizably Ciara St James flavor of romance.
