I do not think I can express to you how good this book was. but I am going to try to.Spellbinding, beautifully written and completely transporting is the way I would describe it. I had read Robin Wasserman’s other books and I enjoyed them, but when I heard about her newest book The Book of Blood and Shadow I knew I had to pick it up. I am the biggest fan of mysteries and this is an epic one that spans centuries and continents. It all begins with the book of blood and shadow and letters written by a girl named Elizabeth. Only Nora can see that Elizabeth’s letters may actually be important and eventually life-changing. 'I should probably start with the blood.' is the first line of this book. Are you kidding me? I was drawn in from the first page and brought along on this whirlwind of a journey through Prague and essentially through time. Let me tell you, I never knew who to trust! Once, like Nora, I thought I knew what was going on something would happen that would throw me for a loop. And then that perception would get changed, it was so much fun. I loved learning about Elizabeth and her story, learning what happened to her and how she got tangled up in all of this was so exciting. Even though we only got to see Elizabeth’s actions through the letters that Nora translates I really felt as if Elizabeth was another main character who was brought to life in such an interesting and different way.Nora was awesome, I loved her drive and her yearning to find the truth. I also really appreciated that all of her friends helped figure things out. I hate when the main character is the only one who can figure things out. It is so unrealistic. But thankfully that was not the case.PRAGUE! Prague was almost a character in of itself. It was so richly written that I felt like I was there, it also made me need to go there someday. Also secret societies.The Book of Blood and Shadow was more than I ever could have imagined. It left me more than satisfied and hooked the entire time I was reading it. It is a must read and the perfect example of what I mean by A Reader’s Adventure.
