Yeah, it could have had a more solid ending, it felt like one of those movies that ends with "Sequel Alert!" especially with her dad and the woman he helps with her stuck car, etc. It was kinda like "Where'd THAT come from?" and why do we get to know about that, but not about what is going on in the narrator's life now?
As for her age, page 4, third paragraph begins
"I am twelve on this mid-December afternoon (though I am thirty now),"
I did like the book, but still have my objections. But that's okay, I don;t have to love EVERY book I read, and it makes it more fun to discuss things when we all come at it with our own likes and dislikes.
Speaking of which ...
By the end, did you like or dislike
Nicky
Charlotte
Robert (Nicky's Dad)
Detective Warren
And why?
