** spoiler alert ** Wow--this book is so interesting in many ways, but I'm mainly blown away by the fact that I read the whole novel one way, and the very ending makes me question everything I thought I knew. This book demands to be read more than once. I'm haunted by it! I keep thinking suddenly during the day "Well if that's so, then what about X..." I need to go back and re-read with the ending in mind, and see what changes and how different the story is with the ending's information in mind. I LOVE unreliable narrators, but what I love so much about "Rosie Girl" is that the narrator seems so incredibly normal--there's no reason to suspect that she's unreliable. But then at the end we realize that the world we've seen is entirely in her perspective and may not completely reflect reality. Of course, every first person novel is more or less entirely in the perspective of the character, but we forget this. We enter a book wanting to trust our narrator. "Rosie Girl" makes us question everything we've known in such a believable, wonderful way. This book is a definite YA must-read!
