The perfect wedding?

Dr. Fern Rycroft had disappointed the islanders once by not returning to work there, so she agreed to her aunt's wishes that she have an island wedding. But Fern hadn't anticipated two things the actions of Lizzy Hurst, who adored Fern's fiancee and wanted to stop the wedding, and meeting the new doctor, Quinn Gallagher.

Lizzy's antics resulted in mass food poisoning, so Fern had no choice except to work with Quinn, and by the time the panic was over, Fern knew the wedding was off unless there was a chance of a substitute groom?
