I found myself thinking of Necklace of Kisses, and how this book feels like a move further into the "real" world. Unlike the magic world of Dangerous Angels which seems almost apart from our world, this world is definitely ours, with the 2004 tsunami and all. It has premonitory dreams and spirits and such, but in a way which feels more like, "Yes, this could happen in our world."
I found Katrina's development interesting and engaging, but I would have liked the book to end when Katrina finishes telling her story. A lot of the "In Her Own Words" and following sections felt like retelling of Katrina's story but not quite, which was frustrating as a reader, and I also generally found them less satisfying than Katrina's story.
