This book grew on me!
My first impressions were less than totally enthusiastic, I hated the character of Muriel and I could see the plot arc so clearly; crusty unlikable Grandmother becomes lovable once you know her backstory. Well, that proved to be correct but while at the start I kept thinking that nothing would excuse her neglect the book scored points in that it never tried to make them excusable, only explicable.
I didn't like Jack-the-love-interest. Obviously Jen was going to ditch the Manhattan fiance and end up with Jack on the island. But I didn't like him and I felt sorry for Jen who was going to exchange one arrogant, uncaring, stuck up doctor fiance for another model of the same. Sure, she was indubitably better off with Jack, because that way she gets beaches with turtles laying on them, surfing and an island lifestyle rather than a sterile, money grubbing lifestyle. Still, I liked Jen and wanted better for her. In fact, I never actually took to Jack that much, I tried to excuse his behaviors by telling myself that it is just an example of Australian anti-tall-poppy syndrome, but no, he was a boor. Still he was well written, fitted with Jen and was superbly suited to the story, so really I didn't have to like him.
Also right at the beginning. The theme of shipping the dog to USA, then turning around and sending him straight back.... My mind boggled. This author is Australian, has she no idea of the fact we have among the strongest, harshest incoming quarantine laws in the world? This plot line took ludicrous to a whole new level.
Despite all these (and more) annoyances and aggravations this book charmed me, while it is classed as a romance, and there is a romance element to it, there is so much more to this book than just Jack and Jen going up the hill to fill a bucket of water.... I loved the descriptions of Muriel and Jen coming to the island, Nautilus Island itself charmed me entirely and while I am pretty sure it is entirely fictitious, the pictures of it that this book painted in my mind are stronger than of some actually places I have really visited.
While Jack stayed an Ahole, Jen's growing connection with him based on her unknown grandfather and the medical situations that arose on the island during her stay made for a very believable buildup of association and experience between them. Also, it made the population of the island rich, varied and interesting to the reader; I really, really enjoyed the large number of characters in this book. They felt so very real!
I also loved the descriptions of the beach and surfing, the little surfing dictionary that started each chapter and the way the story was never that far from the ocean.
These things that I enjoyed made it possible for me to ignore the ludicrous (that word again) preamble to the ending, with Jen babbling idiocies like she was a stoned moron, Jack carrying on like an idiot and that cringeworthy "turtle giving birth"... thingie.... I don't even know what that was meant to be.... *cringe and skim read till it is mercifully over* However that the end was kind of adequate (and on a beach) did make it possible to overlook that and other regrettable portions of the book. Overall I was very happy with it, I might even re-read one day.
