I failed to get involved in the storyline, it seemed too reminiscent of the stories of Baba Yaga and her house on chicken legs that lives in many dimensions. (In Slavic folklore, Baba Yaga is a supernatural being who appears as a deformed or ferocious-looking old woman. Baba Yaga may help or hinder those that encounter her or seek her out). So having read stories about Baba and her disciples before and quite enjoyed them, I needed to read a story which was completely different – except this one wasn’t. And death magic is quite common too in stories and comes across better in a humorous format I find.
This is my personal view as someone who reads and has already read, far more than the 10,000 lifetime books – as I read 400 books a year. So you really have to be good and original especially when delving into folk-lore or fairytales.
