This is the sequel to The Black Prism, a book I enjoyed. The fantasy world is interesting and fully realized; those gifted with magic can use the various colors of light to create objects. The main character, Gavin Guile, has the power to use all of the colors and is the Prism, a kind of ruler. The action picks up where the previous book left off, but it was obvious to me that this book suffers from the “middle child” syndrome. Some loose ends were tied up from the first book, but the plot seemed contrived mostly to set up the next book. The best character is Kip, Gavin’s illegitimate son, who has a coming-of-age story in the storyline. The plot, as a whole, seemed disjointed and full of filler and redundancies. This is a 600+ page book that could be edited into something much tighter. Reserve it!
