Everyone on Dunmore Island had a reason to want Margaret Calloway dead.

The groom's mother had spent thirty years quietly collecting secrets ? blackmailing her way through weddings, business partnerships, and old friendships, filing the evidence away like insurance policies she never planned to cash out. Until now.

Event consultant Nora Walsh wasn't supposed to be investigating anything. She was supposed to be drinking champagne at her best friend's private island wedding and politely avoiding the setup that had been arranged for her. Instead, she's standing in a rose garden at dawn over a body, holding an anonymous note someone slipped under her door before the murder happened, and facing a list of suspects that includes the bride, the grieving groom, the best man, and the detective who just stepped off a morning ferry.

The same detective she once had the best date of her life with.

The one she ghosted two years ago.

That detective.

With the island locked down and no ferry until Sunday, Nora has forty-eight hours to work out which of the ten people trapped on Dunmore Island struck Margaret Calloway down in the rose garden ? before whoever did it decides that Nora knows too much to leave on the 2pm boat.

Six suspects with secrets worth killing for. One detective who thinks she might have done it. And a killer who knows she's getting close.

THE PLUS-ONE PROBLEM is a compulsively readable murder mystery romcom set on a tidal island off the Georgia coast ? Knives Out energy with a slow-burn romance at its center, and a moral gut-punch of an ending that will stay with you long after the ferry pulls away from the dock.

For readers who want the puzzle AND the love story. You don't have to choose.

Standalone. Complete.
