A weeklong "no-strings-attached" vacation fling turns into an enduring love in this sweeping romance from New York Times–bestselling author Carolyn Brown.

Monica Smith's a superstitious librarian from Texas who's always lived by the books, never daring to go beyond exactly what's expected of her. Tired of her daily routine—and ever-so-slightly jealous of her famous sister, Fiona—she's desperate for a change of scenery. So when she comes across a brochure for a beachside vacation, she boards the next flight to Florida, seizing the opportunity to unwind and be completely on her own for once. That is, until she meets him.

Spencer Hamilton's a strapping divorcé from Louisiana who can't help but play hero when he notices Monica struggling to lay her blanket down in the sand. As the two bond over their similarly timed solo trips, a spark ignites between them that inspires Monica to try something completely foreign to her: a fling. Having agreed to an arrangement wherein they can't share personal details nor form any deep attachments, Spencer and Monica spend their days walking by the ocean and their nights tangled up in sheets, falling headfirst into a passionate love affair neither of them will soon forget.

But soon it's the end of the week and they must face the reality of going their separate ways. Spencer returns home heartbroken, only to begin a desperate search for the striking woman who's taken up residence in his mind. Meanwhile, Monica's swept off on a journey of her own when Fiona suddenly appears on her doorstep, begging for help. And as the sisters work to mend their long-neglected relationship, Monica suddenly finds herself in a situation that might just reunite her with Spencer. But for someone who believes so firmly in fate, she can't help but wonder, What are the chances lightning will strike twice in the same place?
