What if what happens on holiday doesn't stay on holiday? When mousy factory-worker Lilith Monroe meets gorgeous Will Taylor on holiday, she reinvents herself as Lily, a risk-taking costume designer extraordinaire. What’s the harm in a few white lies when she’ll never see Will again? Back in England, Will can’t stop thinking about Lily. When his events company needs a costume designer last minute for the Royal Windsor Festival, it’s like fate is knocking on his door – he can hire Lily and see if the spark is still there. Except he hasn't been entirely honest with Lily... Can a holiday fling become something more, or are there too many untruths between Lilith and Will?
