Query: unasked for and unneeded

The Belgariad is considered an epic by most, and the Mallorean is a welcome continuation. "Belgarath" and "Polgara" were reasonably interesting, but not this one. The Rivan Codex is contains such trivialities that the authors had forgotten to include in the books, along with tidbits that no one really wanted to know. It seems as though the authors are milking the cash cow that is this series as far as it can go. Read the first ten books of the series, and the two following if you wish, but this book is by no means a necessary addition to your library.
