This is Book 2 in The Mercer Brothers Series, but can be read as a standalone. She broke his heart five years ago. Now she needs him to pretend it never happened. When Sienna Chen panics and tells her dying father she's engaged, she knows there's only one man who fits her father's impossible standards: Declan Mercer, the man she walked away from without explanation five years ago. Declan has spent years burying the pain of Sienna's sudden departure. He's thrown himself into his role at Mercer Technologies, convincing everyone, including himself, that he's moved on. But when Sienna's late-night call shatters his carefully constructed walls, he agrees to her desperate request on one condition: after the weekend is over, she tells him the truth about why she left. One weekend. Three days of pretending. A lifetime of unresolved feelings. As they navigate family dinners, vineyard walks, and a shared bathroom at her family's Napa estate, the lines between performance and reality begin to blur. The chemistry that once drew them together hasn't faded. And the secrets Sienna has been keeping might just explain everything, or destroy any chance they have at a second chance. With her father's health declining and old wounds resurfacing, Sienna must decide if she's brave enough to finally choose love. And Declan must ask himself: is the truth worth the risk of falling for her all over again? The Fake Fiancé is a second-chance romance filled with family drama, emotional depth, and the kind of slow-burn tension that will keep you turning pages late into the night. Perfect for fans of Elena Armas, Emily Henry, and Christina Lauren. This is Book 2 in The Mercer Brothers Series, but can be read as a standalone.
