this was a great follow up! Cate's shoulders are heavy with responsibility to her sisters, her fellow witches and to the community. Not only is she having to push up against her sister, but also has to deal with internal splits in the Sisterhood. The Brotherhood is condeming young girls left and right as well as taking away all their freedom bit by bit. Its great to see how Cate eventually shoulders her burdens and takes lead to protect the ones she loves and the innocent. 
 Really looking forward to the next installment to this trilogy.
