It's somewhat amusing to see all this effort over whether a dude in prison can read an awful book about a chick who kills warewolves. The book -- "The Silver Crown" -- is available for one cent (used) on Amazon. Seventy seven cents if you want it new.
I'd easily have sent the guy a free copy if it'd have saved the expense of the appeal.
For what it's worth, I think that Justice Richman's analysis seems pretty spot on. At well as somewhat humorous. The book has "some" literary value. Though notice that this word is in quotes, 'cause we're definitely not talking about Shakespeare. The best that can be said for the book is that (1) it's not really all that different than all the other crappy vampire-slash-witch-slash-warewolf literature that's out there, and that (for some inexplicable reason) people tend to consume these days, and (2) yes, there are definitely "screw" scenes -- let's use the fancy term and call those components "erotica" -- but the literature part isn't merely "filler" purely intended to keep the work from being obscene. The thing is an integrated whole. An absurd, messy, utterly implausible and silly work of literature, but a work of literature regardless. So Martinez is entitled to spend his time in prison reading this dreck and fantasizing about a hot warewolf-killing babe if he'd like.
