This will be a short collection of my thoughts as I don't want to repeat my review for book 1. 
 The ambitious premise of book 1 continues in Blood for Blood and the writing quality is consistently high. 
 I did feel that Yael became more of a character in this book, whereas in the first she was more an empty shell, an instrument for vengeance. 
 And speaking of characters... (view spoiler)[Why, oh, why do authors feel the need to kill off their best character? Why?! (hide spoiler)] 
 The ending felt a little lack-lustre to me, even thought it made perfect sense and was respectful. 
 Overall: this was fine and a fitting conclusion, even if I did feel the story tailed off rather than giving us a truly satisfying ending.
