Although she has grown up in a strict religious community, Earth's life up until now has been a happy one, but life with the older man to whom she is betrothed is no longer where she sees her future. So when she secretly leaves she knows she will never return, despite having nowhere to go and knowing no one in the outside world.
Stowing away on a luxurious but empty yacht, Earth is discovered by Robin, its owner, and there is an immediate spark between them.
But Earth's upbringing and naiveté, combined with Robin's past experiences, means that any relationship which might develop between them might hit a few snags. Add in ex-wives, ex-fiancés, along with any number of misunderstandings and misheard conversations, and whatever happy endings might be possible for the mismatched couple will have to be hard-earned.
