I didn’t care for Fairy Tale at all either. None of the characters were interesting or memorable, it took too long to get to the Fairy Tale world and it was as compelling as the characters (not compelling at all), and I also really hated the ending for the same reasons as you.

There was one saving grace in the book for me: The tournament. Forget what they call it but it was the only highlight. The training, competition, and escape had me riveted and eager to see how it would go.
