I enjoyed the story but it was not as exciting as some of Starr's earlier books in the series. The pace was slow and the howdunnit didn't grab my attention. While the howdunnit was interesting I don't think the writing was well executed. Singleton spent alot of time trying to figure out how someone could collect enough urine, dove droppings and a small amount of charcoal to create the substance that killed Sabyn. I was eating dinner while I read the book and that urine section didn't set well with my tummy. I did find it interesting that the deceased was copying a gospel into English while John Wycliffe, who translated the Bible into English between 1382 and 1395, denied any knowledge of it. Our protagonist did not perform any surgeries but did gather herbs for several people to help ease the pain of the plague.
3 out of 5 stars.
