I'm reading another Hilderbrand Novel

I'm reading  The Matchmaker by Elin Hilderbrand.  The writer, Hilderbrand, has her main character  Dapney be a well known matchmaker on the island of Nantucket.  At first I didn't know if I liked the coincidence of how all the couples she's matched together are highly successful individuals who just so happen live on the same island.  The characters, for example are professors who write million dollar research manuscripts and Pulitzer prize winners.  One such matchmaking is a doctor  who helps the protagonist with her own rare condition called the inability to leave the island of Nantucket which I also felt bazaar but for some reason the plot seems to fit the novel and its very intriguing.
