Lainey Sullivan is happy with her life as a schoolteacher, going to church and playing at weddings as part of a string quartet. But one wedding changes everything, because the best man is Nick Cusack, and she’s the girl he left behind in his search for pop stardom.Nick is thrilled to reconnect with Lainey, and can’t believe that a simple mistake like the wrong address has kept them apart for the last ten years. His band, The Mavericks, have reached the peak and he has an emerging acting career. As they begin dating, they both find that all the feelings are still there. And so is the thing that has the potential to part them: Lainey’s Christian faith, and Nick’s unbelief.A Simple Mistake is the debut novel from Australian author Andrea Griggs. It’s a sweet tale of love lost and love rediscovered, but it’s much more than that. The old saying is that the path of true love never did run smooth, and that is certainly the case for Lainey and Nick. Lainey has a secret that she is afraid will destroy the relationship, and there are other forces that might keep them apart. While A Simple Mistake follows the conventions of the romance genre, it doesn’t do it the easy way. Both Lainey and Nick have a road to travel before then end. They each have decisions to make, decisions that aren’t made overnight.Australian Christian fiction isn’t quite as sophisticated as American Christian fiction, but that means it has a realism that is often missing in the highly- polished American offerings. And that realism is why I found it so enjoyable.Thanks to Andrea Grigg for providing a free book for review.
