The story by Mercedes Lackey was written at the age 13 and below level. Very juvenile and predictable, and about on a par with her Gryphon series, particularly the second and third book. I felt as if she was just hacking the story out to have something to offer during this time period. Her characters were way too wooden and without interest. The other two stories by Tanith Lee and C.E. Murphy failed to hold my interest past the first three or four pages, and I'd have a hard time telling you what they were about. This just isn't worth the money.
