ABOUT THE BOOK: Release Date July 16, 2026
The marriage was never about love. It was about power.
Quinn Delaney becomes a bride only after her sister walks away, and two syndicates need the problem fixed. She is quiet, careful, and replaceable. Exactly what the alliance requires.
Lorenzo Mariano is the most dangerous man in the room, and he never pretends otherwise. He gives Quinn his name, his protection, and his rules. He keeps his distance. He expects her to survive it.
She tries. But being overlooked hurts more than being hated.
When lies from Quinn’s past reach Lorenzo before the truth can, the distance between them turns to ice. He married a stranger. Now he’s not sure who he’s living with.
He never promised to love her. He promised not to care.
Breaking that vow may cost him everything.
Keeping it will cost him her.

REVIEW:RUTHLESS VOW is the first instalment in Brooke Summers’ contemporary, adult BOSTON ELITE SYNDICATE erotic, dark, mafia romance series. This is Quinn Delaney, and Lorenzo Mariano’s story line. There is a prequel novella THE CAPO’S YULETIDE BRIDE that focuses on Cesare Mariano’s, the patriarch of the Mariano Crime Family.
NOTE: Due to the nature of the story line premise, there WILL BE triggers for more sensitive readers.
Told from dual first person perspectives (Quinn and Lorenzo) RUTHLESS VOW follows the arranged marriage between our story line couple. The four remaining crime families of the Boston Elite Syndicate are desperate to forge a power alliance, an alliance built through family and marriage. The first arrange marriage between Lorenzo Mariano, and Daire Delaney fell through, and eighteen year old Quinn was offered up by her family as second choice. From the outset, Lorenzo offers his home and his protection but refuses to become emotionally involved until he discovers a dangerous truth about Quinn’s past. Meanwhile, each of the crime families have discovered a rat, a mole within their organizations, and Lorenzo is about to uncover a connection to everyone involved.
The world building follows two intersecting pathways. As Quinn and Lorenzo navigate a marriage of convenience, someone is working behind the scenes to destroy our story line heroine but as the threats continue, the tepid relationship between the crime families is threatened as each will discover a betrayer in the midst.
The relationship between Quinn and Lorenzo is acrimonious at best. Lorenzo doesn’t trust or like the woman offered up for his bride but Quinn has been trained to be a dutiful wife , yet observant and caring. When Lorenzo orders his men to do a deep dive into Quinn’s life, what they discover changes the way Lorenzo looks at his young bride. The $ex scenes are intimate and passionate.
There is a large ensemble cast of colorful, questionable and edgy secondary and supporting characters including several members of the interconnected crime families. We are reintroduced to Lorenzo’s extended family: Father Cesare and his wife Vittoria, and siblings Ciro, Elisabetta, Valentina, Sofia and Giovanni. We are introduced to Quinn’s family, a family who have treated our heroine with disdain and control-parents Bridget and Ronan, and siblings Daire, Caden, Conor, and Daithi. The requisite evil has many faces.
RUTHLESS VOW is a story of secrets and lies, betrayal and vengeance, power and control, jealousy and abuse, family and relationships, acceptance and love. The character driven premise is heart breaking, emotional and dramatic; the romance is limited but seductive; the characters are charismatic, determined and dynamic. RUTHLESS VOW ends on a cliff hanger-you have been warned.
