I’ve read the second book, Magic Burns, before, but never officially reviewed it. You can find my full review here.
“[T]he authors are also a lot more comfortable with the idea that their series will continue, and we get satisfying information regarding Kate’s history and magical abilities. It’s obvious that they have a direction in mind for her as well, because hints are woven in regarding plot directions I know the series takes later. In addition, this book introduces us to two characters close to Kate who will be around for the long haul, showing Kate’s softer side without ever diminishing from her overall badassery.”
