The characters are a bit strange. I get it that she went back in time and that explains the way she thinks, but having a literally baby speak was kinda weird. She wasn't saying full coherent sentences, but it was weird to see someone who's clearly supposed to be an infant talk well enough and use "grown-up words" When she turns five I begin to like her character a bit more, but she continues to do things that should be seen as abnormal. She starts her own business (which her parents have no problem with... wtf?), argues with adults (it's like her hobby), etc. She's five years-old!!
When at times you can ignore the ridiculous things, the story isn't that bad. She does all these things to help aid her family which I think is nobel. She goes out her way to help emotionally inept kids.. I like the novel, but I wouldn't rush you to read it. Take you time.
