Isla Rhys has lost her flat, her fiancé, and her faith in the possessive apostrophe-all in the span of twelve minutes.

When her Oxford academic fiancé dumps her via a text message that reads "Your to intense," Isla doesn't just mourn the relationship; she mourns the grammar. Needing an escape where syntax doesn't matter, she flees to her cousin's chaotic home in Bracken Cove, Maine.

Her plan? Write her thesis, avoid human interaction, and maybe start a high-brow book club to bring some culture to the locals.

But Bracken Cove isn't the quiet refuge she expected. It's a town run by a PTA president who weaponizes spreadsheets, a four-year-old who believes rocks have feelings, and Frank Hollis-a rugged, flannel-wearing mechanic who fixes boats and seemingly hates conversation.

Isla is ready to write Frank off as a grunt, until she discovers anonymous notes scribbled in the margins of the town's library books. Brilliant, poetic, heartbreaking notes. As she falls for the mind of the mystery writer, she finds herself clashing with the mechanic who keeps challenging her worldview.

When the truth about the notes comes out, Isla has to decide: Does she want the perfect life she thought she wrote for herself, or the messy, "ungrammatical" love she found in the margins?
