Honestly, this was boring, and kind of bad. For a book about witches and magic, there was very little of either. I actually really enjoyed the first one, A Discovery of Witches: A Novel (All Souls Trilogy) - Deborah Harkness , it was a good "beach book." You know, kinda mindless, pace moved pretty quickly, kinda fun setting, but this one, blergh.
I was going to write a fuller review, but I think tl;wihr* will suffice.
