The Devil's Orchard - Ali Vali

In book five of the Casey Family series, Cain and Emma are planning a wedding before the birth of their third child. Cain has done everything possible to protect her family and get their lives back to normal. Cain is strengthening her partnership with the Jatibons and Carlotti families, as well as trying to help her cousin Muriel heal from FBI agent Shelby Phillips's betrayal.
But nothing can distract her from hunting Juan Luis down to make him pay for trying to take Emma from her. That is the most pressing problem to be dealt with before she can truly enjoy the life and family she and Emma have together. Those plans are derailed with the arrival of someone who not only challenges her place as her father, Dalton's heir, but also her belief and loyalty to the man who raised her.
