My idea for a new Harper's Island

I had an idea for a follow up to Harper's Island. Tell me what you think.

Abby Mills now going by Abby Driscoll is a single mom of two young children. A Boy named Charlie(4) and girl named Shea(3). Her husband Gary "Supposedly" got killed in the middle east since he was an army ranger. She's also the sheriff of the island. It's been 7 years since the Wakefield murders. A family comes to the island to celebrate both a wedding and a graduation. And this family has some secrets. Also a man comes to the island looking to be deputy. But there is something he his hiding. Now the killings are starting up again. Abby is going to have to relieve the horrible nightmare all over again. To figure out this killer.

Abby Mills aka Abby Driscoll: Elaine Cassidy

Gary Driscoll: Bradley Cooper
