Happy Head is a thrilling book with exciting and unexpected twists  

I loved this book, it is impossible to put down, I ran into an embarrassingly large number of walls because of this. I loved most of the characters in this book (some are unlovable), all of the characters were interesting and different from each other. My favourite character was probably Mark because he seemed like a really nice guy unlike most of the people in this book.

I would recommend this book to anyone who enjoy young adult thrillers and I am so excited for the next book in the series.
