Blaxill has portrayed the characters so that the reader comes to know what personality they have. By doing this, the reader becomes closer to the character and understands the reason behind their actions.
Throughout the book, it switches between the main characters, Jonathan and Rosalind, so that we can learn about them both, and read about how their lives become entwined. And comparing both characters, you begin to realize what similarities and differences they have, creating a friendship that we see grow throughout.
However, in my opinion, I believe the action part in the book could have been longer, so that it captures the suspense in the event.
Pretty Twisted is a book about growing up, differences and friendship. A must read for anyone who loves a bit of drama!
