Emily Alyn Lind’s Cadence Sinclair, who narrates the book We Were Liars and the first season of the show, will be back at the island off the East Coast as well. “As she digs deeper into family secrets, she learns about the Sinclair Sisters’ summer of 1999 — a summer rife with first love, rivalry, and even murder,” the logline reads. “In flashbacks, we see Carrie (Lapaine), Penny (Roorbach), and Bess (Wolfe) navigate their own teenage summer, as they come to terms with their past in the present day.”

Dempsey Bryk, who plays a character new for the show, Ebon, has been upped to a series regular for Season 2. Described as a rough-around-the-edges Boston guy who spends his summers among the blue-blooded elite, captaining a charter boat for senators and celebrities,” Ebon will be back on Martha’s Vineyard after losing his love interest Mirren (Esther McGregor) last summer.  

“He’s got a fresh chip on his shoulder and absolutely no interest in being pulled into rich people’s sordid secrets — but it’s hard to avoid in these murky waters,” his character description and logline read.
“They’ve told me a little bit about the arc of the character,” Bryk told Deadline at SXSW Film Festival 2026, where his directorial debut Crash Land, premiered. “They’ve told me a little bit about the arc of the character. I’m really excited. It’s something new, but it feels really authentic to how they wrote him in the first season.”
