Okay, the book is aimed at children so I've adjusted my expectations accordingly. I found it interesting that the story was about twins who were descended from Snow White. It's an unusual angle. The conflict is set up early as neither is sure which was born first and is entitled to inherit the barony.
The one thing I didn't like is that the writing seemed to skip from one thing to another, like an old Vinyl record that needs cleaning. I think smoother transitions and more continuity would have made it a much better book.
The writer seems to assume that the reader will already know all about the wicked queen and Snow White, which is probably true for the majority of readers but maybe not for everyone.
Overall it was a pretty good book and I'm sure that children will enjoy it, plus there are some ageless lessons about the temptation that power brings and how it can corrupt. 3 stars out of 5 from me.
