On the same day Reese Witherspoon's book club announced it's 101th pick, the actress and entrepreneur excitedly shared she's also co-writing a book with Harlan Coben! I don't know what readers across America have done to deserve this, but we welcome the news with open arms. Reese has a keen eye for choosing invigorating reads — and turning them into fantastic projects beyond the page — so it totally makes sense she's putting her experience to good use by partnering with one of the world's creative mystery and thriller book authors.

Here's everything we know about one of the best pieces of news to come out of 2025.

Reese Witherspoon shared the news with eager fans on Instagram by posting a photo of herself smiling next to Harlan Coben. Based on their wide grins, they seem eager to be able to share this secret. We're only calling it that because there's no way we could've predicted Reese would be one-half of a writing duo next year!

She said, "To say I am a fan of Harlan’s body of work is a massive understatement… the fact that he found my idea for this thriller intriguing enough to want to partner with me on it as co-author is a dream becoming a reality," (via The Hollywood Reporter). Harlan followed up with, "Be it acting, producing, creating and even book-club selecting, Reese’s instincts about storytelling across all media are unrivaled."

Authors Lucy Foley and Stacy Lee both expressed excitement with both of them expressing how much they "can't wait to read" the upcoming book.

What's the book about?

Since the book won't be published until next fall, details aren't readily available. We can suspect that it'll be a mystery or thriller book based on Harlan Coben's previous body of work. Still, we can't wait to devour what's sure to be a gripping story!

Reese Witherspoon held Hello Sunshine's Shine Away event over the weekend where she dished about her upcoming book with Harlan Coben. "I had the idea two years ago and then I approached Harlan Coben probably eight months ago and I was like, ‘Am I crazy?’ He said, ‘This is a really good idea Reese,’ so I knew I was onto something," she told the attentive audience (via The Hollywood Reporter). Eventually, Reese and Harlan "started brainstorming together" which resulted in them co-writing the book together.

Though she's shocked Harlan "agreed" to co-write the book with her, Reese trusts Harlan's judgement and creativity because she feels "he's an incredibly accomplished writer." According to her, it's been "really fun to collaborate" together.
