Will I be the only person on /lit/ who buys this when it comes out?

Most likely, yes, OP. This isn't a board known for celebrating popular literature, nor is it particularly interested in genre, at least in the manner that Brown and his ilk explore it. You're better off sharing your thoughts on /x/, of all places, considering the goofy machinations Brown employs to come up with sub-par commentary on contemporary institutions. It's tedious reading, and few (if any) people here will care if you make another thread once you finish it.

already pre ordered it

I don't have anything against pop lit.
I do however have something against one trick ponies.
ie Writers who had one massive hit and then just figured "Fuck it, I will just write that book 10 more times because people are stupid and will keep buying."
John Grisham and Nicholas Sparks also apply to this.
But if you enjoy it, go for it OP.
