Cal Vandeusen

Cal Vandeusen (played by Adam Campbell) is Chloe's boyfriend and a doctor. He's a charming British outsider who doesn't know anyone in the wedding party, but tries to fit in with the tight knit group.

Chloe Carter

Chloe Carter (played by Cameron Richardson) is one of Trish's bridesmaids. She's sexy, playful, impulsive and always looking for ways to live life to the fullest.

Christopher Sullivan

Christopher 'Sully' Sullivan (played by Matt Barr) is Henry's best man. All of his friends call him Sully, and he has lots of friends. He's a fun-loving frat boy at heart whose good buddies live vicariously through his many sexual escapades.

Now he returns to the island as the fiancé to the mogul's beautiful daughter, Trish Wellington.

J D Dunn

J.D. Dunn (played by Dean Chekvala) is Henry's brother. He's a dark and brooding loner with tattoos all over his body that speak more to his true nature than he ever lets on in conversation. Being the only brother of the groom should have made him a lock for "best man," but J.D.'s barely a guest at the wedding and wouldn't mind just missing it all together. His childish antics make Henry's life more difficult, and sometimes there's a malevolence in them that makes everyone wonder if J.D. has some secret endgame.

Thomason) is a local fisherman who couldn't be happier about the Wellington-Dunn wedding coming to Harper's Island because it brings Abby, his high school sweetheart, back to the island.

The years have been difficult for Jimmy, and he did some things that Abby will find very surprising.

link

Katherine Wellington

Katherine Wellington (played by Claudette Mink) is the very definition of a trophy wife; a sexy woman closer in age to her stepdaughter than her husband.

Madison Allen

Madison Allen (played by Cassandra Sawtell) is Shea and Richard's daughter. She's cute, sweet and, at times, horribly spooky. Lots of kids enjoy mischief; Madison might enjoy it a little too much.

Malcolm is trying to start up a business to mass-produce his microbrew, Sacred Turtle. His friends are very supportive emotionally, but lack the funds to finance his endeavor. His inability to raise capital has put a lot of stress on Malcolm, and made him desperate enough to do things his friends would never suspect.

Shane Pierce

Shane Pierce (played by Ben Cotton) is a Harper’s Island local who pretty much dislikes everyone.

Shane’s got a short temper and a history of violence, which makes him capable of just about anything.

Shea Allen

Shea Allen (played by Gina Holden) is Trish's big sister and the Matron of Honor. From the outside, she appears to have it all - a great husband, a beautiful daughter and all the money in the world.

link

Sheriff Charlie Mills

Sheriff Mills (played by Jim Beaver) is the law on Harper's Island, the man who killed John Wakefield, and Abby's father. He ended Wakefield's deadly rampage seven years ago, but not before Wakefield took the life of his wife, Sarah.

But times have changed, and Sheriff Mills has some dark secrets he has no intention of sharing with his daughter.

link

Trish Wellington

Trish Wellington (played by Katie Cassidy) is the radiant bride-to-be who loves Henry Dunn with all of her heart and can't wait to marry him.

Trish doesn't care about Henry's lack of pedigree, but she is "Daddy's Little Girl" and finds herself torn between the two men in her life.
