Grey Sister is the second book in the Book of the Ancestor series by Mark Lawrence. The story continues a few years after the first book, Red Sister. Nona has yet to revenge her friend and is feeling guilty and restless. Thankfully in the last couple of years she has graduated to a new class and is improving even more in her skills. Nona is not the best skilled in her class, but she seems to be able to do a little bit of everything. Most importantly, when her friends need her she finds a way to accomplish what is thought to be impossible.

I loved Red Sister, and I loved Grey Sister even more. It is like Lawrence took a step back and decided that he could work in so much more of the back story of the world. The best part is that he did it in a way that flowed naturally in the novel. I learned so much about the world and so much about the side characters. Now I would love a short story collection about all of the people we glance in this series. As much as I love Lawrence's worlds I am amazed by how realistic his characters are. I seem to connect to even the most side of side characters.

I am anxiously awaiting the third, and concluding, book to this series.
