Midsummer Star (Harlequin Romance, 2566)

Facing bankruptcy, Celine's family was forced to turn their home into a guesthouse to make ends meet. Celine found her new life to be a lot of hard work but great fun, too. And she soon met a young man, Nicky, who seemed very taken with her—if only Nicky's overbearing cousin, Oliver, would stop interfering. But when Celine discovered that Nicky was married, she was only too grateful for Oliver's comforting presence. Gratitude wasn't exactly what Oliver had in mind, but it was a start.
