This has a "Harlequin Romance" vibe that would normally send me screaming in the other direction, but given that it's Janet Evanovich, I was intrigued. I read this in a different way than others might, I think. This was a chance to see Evanovich's writing style in its infancy, before she became the publishing phenomenon that she is today, with the fantastically popular Stephanie Plum novels. The humor is there, but a bit more rough, and the romance is more pronounced than it has since become.
Stephanie (see, even that started early on) is in the difficult position of having to be a ship's cook for Ivan, who runs a old-fashioned cruise. You know by the end of page one that these two are going to be together - the fun is in finding out just how that will happen. The resolution is, well, trite. Oh well. It's still Evanovich, and even subpar Evanovich can make you laugh out loud.
