(English is not my first language) Holly Jackson writes in a way that makes you addicted to the story. I couldn't stop reading it at all, I was finished in three days. Even though the main character was sometimes a bit annoying it was interesting to read a character that isn't perfect or doesn't react like a normal person would. The first part was a bit slow but her writing style made up for it. If we include the ending it's definetly a darker story and opens moral questions. In conclusion, it was definetly a very interesting and exciting book, and it's really worth it! So far I've read every single book by Holly Jackson and not a single one disappointed me.
