Wow, this was bad. Sheckley has written some good stuff in his time, so I can only assume that he needed the money in a hurry and wrote this over a weekend. It's pretty much JMS's shooting script in novel form - there's certainly no character or plot insights (contrast this to Peter David's novelization of "Thirdspace", which was a mediocre TV movie, but a much better book). It's not been carefully edited, either - there are many places where word choice is poor, and a sentence or two that really are redundant. It's about the level of work one might expect from a moderately-talented highschool sophomore.
Collectors of B5 books will want this, but I'd recommend others get the video - it's much better on film.
