YASSS! This book was amazing. Honestly I was nervous when I saw how long the book was but I was hooked within the first couple of pages and there was no turning back. From start to finish this book is perfectly paced - some parts flying by and others moving s bit slower to provide important details. This is a gritty, and at times gory thriller that has won me over for Lars Kepler. I will definitely be reading every book in the Joona Linna series. The authors expertly intertwine multiple characters and tons of action and information without it ever seeming overwhelming or irrelevant. Joona Linna is one of the best detective characters I have ever read and I cannot wait to see how he develops over the course of the series.
