The first half of this book is really two stars, but the second half more than made up for it. I'm not sure why I found the first half so dull. There is plenty of action and fast-paced adventure on a Caribbean island, the characters are well-drawn and the opposite of insipid, the dialogue so-so perhaps, but the descriptions of the island great - and yet it didn't quite come together for me. There was no investment on my part until well into the second half of the book. By that time I was really pulling for Charlie and hoping he would be successful in all his endeavors and Penelope had become a bit more human and less abrasive, although during the first part of the book I was cheering HER on and more sympathetic to her plight than Charlie's. There are two great sub-plot romances going on here, too, so it should have been perfect, but somehow it just didn't grab me the way Blue Clouds did.
