In The Book of Blood and Shadow, we follow Nora (hehe), a smart senior/Latin nerd at a prep school, and her three best friends. They land spots in a special study class to try to interpret a book that no one has been able to in the 400-some years since it was written. It turns out that an organization is keeping and eye on everyone who shows interest in the book, and once they start to make progress things start to heat up.
This is a really long book, and for most of it I thought that it was a really long book for such an okay story. It was an interesting read and the ending really picked up, but I feel like a lot could have been cut. There are several twists and surprises that keep the book moving and really engage the reader.
