This review will be short and spoiler free! :-) 
 This was a gripping whodunnit and entertaining game of cat and mouse. It's a long book but it doesn't feel long; another true page-turner from Lyga. 
 Be warned: the gore and gruesome scale increases significantly in this book. Plenty of entrails all over the place. If just the idea of that turns your stomach, this probably isn't the book for you. 
 But, for all it's good points, I didn't enjoy this book as much as I Hunt Killers. This was partly because as soon as we are told the markers the killer is leaving behind, I knew what was going on. And I couldn't believe that no-one else got it either! 
 The other reason why this is a 4, rather than 5-star read for me was because the characters did some things that were truly daft. Unbelievably daft. Sighing and rolling your eyes at their idiocy daft. 
 But blimey what a cliffhanger! I'll be reading Blood of my Blood asap.
