The Billionaire and the Hitman's Daughter (Refurbished) TBHD

Set in 2022, the romance book revolves around the love life of its major character, Bruce, who is a CEO of his father's company in the US.
He had a dysfunctional childhood following the assassination of his mum, Jacqueline, when he was just 8 years old. His father, Harrison, couldn't be the family and comfort that he needed as he struggled with grief and sent his young Bruce to a boarding school in the UK.
Bruce's childhood caught up with him as he grew up, nothing short of a full blown narcissist who never gave the idea of love a chance. This changed when Imelda walked into his life.
Imelda, a fervent Catholic of Russian descent is modest and Bruce is everything she normally wouldn't want in a lover. Imelda had her own share of dysfunctionality growing up. Her parents, Eugenia and Yakov were divorced when she was four years old and her father was imprisoned not too long after. She grew up not having the life she'd have considered perfect for her. Imelda is an author who also waits tables at VIP events.
After fate plays out while the book unfolds, these two become a couple, defeating villains and mini-villains along the way too.
In the end, they clinch the happily ever after life they so much fought for. The story reaffirms the reader's hope in the existence of love that's capable of defeating trauma and surmounting challenges.
