The first thing you need to know (given my current obsession with Narnia) is the Lucy of this book is not Lucy Pevensie!
Dear Lucy by Julie Sarkissian
My rating: 1 of 5 stars
There are things I like about this book - the main narrator (there are three, but the developmentally-disabled titular character takes up the majority of the book), and the talking chicken.
Other than that, this book is full to the brim of WTFery. The true story of what happened to Stella at the hands of Mister, seemingly choreographed by Missus and of which we never get the full details but we see enough to guess at the true horror, is the main one but Lucy's mother appears to be an absolute piece of work as well.
I don't think this is a book I ever want to re-read.
