Review: Read Orbs first

I can't deny that this was good.  I enjoyed it.  Having read Orbs, it added to the story but I didn't rate it higher because I'm not a fan of these little stand-alone books that really should have been written into the main story itself.  It's not a prequel in the sense that there was a full story to be told, it's an expansion on something partly covered in the main book.
