I've been stocking up on Halo today by listening to the soundtrack, and was thinking to myself: are the books as good as they sound?
I have seen them in Barnes & Noble and wondered what they were like, so I ask you:
Are they worth the money to buy?
I follow criteria in buying books: (I am picky.

An entertaining book that you can read for hours. (Like Jurassic Park by Michael Chrichton.)
I would prefer to keep the language to a minimum, for instance, one book I read was so bad, there was almost one in every paragraph. (Fragment)
Descriptive; MUST HAVE! The last one I read was like licking a mummy. (Dracula)
Length would be preferable, for it keeps it fueled instead of drawing all of this momentum at the start, and have a short ending.
Do the Halo books provide these? Or should I get Exodus instead or along with them?
