Who Is Author Carley Fortune?

Fortune started her writing career as a journalist for Canada’s The Globe and Mail and Toronto Life, before releasing Every Summer After as her debut novel in May 2022. (Her followup Meet Me at the Lake has been optioned by Prince Harry and Meghan Markle’s company Archewell for a potential movie adaptation.)

“I couldn’t be more excited about this fabulous cast,” Fortune said in a statement in July 2025. “This is an enormously talented group of actors, whose auditions made me laugh, swoon, and cry. I know they’ll have fans of Every Summer After falling in love with their favorite characters all over again.”

The Every Year After showrunner was a coproducer and writer for Sex and the City, in addition to developing its prequel spinoff, The Carrie Diaries. Harris’ impressive resume includes a consulting producer credit on Gossip Girl and producing HBO’s recently-revived Lisa Kudrow comedy The Comeback.

Harris cowrote Lindsay Lohan and Chris Pine’s 2006 romantic comedy Just My Luck and, more recently, was showrunner of Prime Video’s survival thriller The Wilds.

According to The Hollywood Reporter, Harris replaced Leila Gerstein (The O.C. and The Handmaid’s Tale) as Every Year After showrunner in July 2025.
