Never have I been more on the edge of my seat for an entire book before but this book has managed to keep me hanging off every word. There are parts that are just a few sentences but have had more weight behind them than a runaway train. This book is literally a “wild train ride” and the fact that the floor was train themed just made everything better. Everyone has what feel like their character arc’s and the more little info you get about Carl’s backstory makes me more attached to his character. I can’t wait for book 4 to be another slam dunk 5/5 star book
