Masques - Briggs, Patricia

Masques is a story about magic. This book is populated by wizards and shapeshifters and other things magical.  An evil ae'Magi is trying to steal all the magic in the world.  A shapeshifting spy and a magician on the run may be all that stands in his way.  This is Briggs' first novel, revised for a second release.  Very highly recommended.
