Twist of Fate by Karly Lane

At twenty-nine years old, single, living in a very small country town, and working in the same job she’s had since she left school, some would say Bel Buckley’s life is mediocre at best.

But Bel is content and always escapes to her beloved romance novels whenever she feels a bit lonely. No matter how hopeless a situation seems, there’s always a hero to swoop in and save the day with a happily-ever-after at the end.
Despite her best friend, Emma, trying to set her up with every eligible man in town, no one holds a light to Bel’s perfect hero: Jax Lexington. Bel owns every book in the outrageously romantic series and loves them.
Emma is concerned about her obsession, but Bel knows the line between fantasy and reality … until the day Jax Lexington arrives in town.
Her fictional hero is real – and he’s best man at her cousin’s wedding.
