Written by the other authors as a sequel to the Witches of Karres by James Schmitz which is a wonderful book. This isn't. Maybe if I hadn't read the other first...
This book is a continuation of the series began by author James H. Schmitz in the '60s. I love Mercedes Lackey and this book does not disappoint!
Not as good as the first book (Witches of Karres), but still a fun romp.
