Dominoes by Phoebe McIntosh

A tender and provocative debut novel about a mixed-race British woman who makes the shocking discovery in the days leading up to her wedding that her fiancé's family may have enslaved her ancestors
"Simultaneously sweet and sobering, this is one you will not want to miss."-Onyi Nwabineli, author of Someday, Maybe
Dominoes opens in London, twenty-nine days before a young couple's wedding. Layla is a mixed-race woman-with a Black, Jamaican mother, and a white father she's never met-and Andy is a white man of Scottish descent. When they first meet at a party, they can't believe how instant their chemistry is, and how quickly their relationship unfolds. Funnily enough, they even share a last name: McKinnon.
Layla's best friend, Sera, isn't so sure about Andy, or the fact that her best friend is engaged a white man. As the wedding approaches, Sera prompts her friend to research her heritage more, leading Layla to make a shocking discovery: It's extremely likely that Andy's ancestors enslaved Layla's in Jamaica, and that the money from that enslavement helped build his family's wealth.
What seemed like a fairy-tale romance is suddenly derailed as Layla begins to uncover parts of her history and identity that she never imagined-or had simply learned to ignore. The process takes her to Jamaica for the first time, where she uncovers truths about her family's history that will change the way she thinks about herself and her future. As the clock ticks down to her wedding, Layla must make a decision: commit to the man she loves or expose a shameful history that has gone unspoken for far too long.
