This is a book in The Sisters of the Otherworld series. It needs to be read in order. The first book is Witchling.
This story is told from the perspective of Delilah. Again, Galenorn does not disappoint. This installment involves a cursed sword; ghost Vikings, and the sisters cousin Daniel.
As always the story is a well balanced blend of character drama and everyday life, intricately woven with the right amount of action and chaos. Plus, several major revelations, and character changes that perfectly make another good read in the series.
