Nate and Reggi
At 18 Reggi and her boyfriend, Cam split up because he was going to college on the east coast and his rich parents didn't think she was good enough. They agreed to meet again when they were 40. Shortly after he left she found out she was pregnant, didn't tell him, and gave birth to a baby girl. Twenty-two years later Molly is in college, and Reggi has moved back to the island to wait for Cam to show up on their 40th birthdays.
There are several intense sections in the book and one I was disappointed in because it wasn't believable. However, the book was easy-to-read, the characters are very likeable, the friends are characters from the previous books so it's nice to keep in touch with them.
I will definitely read the last two books in this series, I enjoy books set in my area.
