How about you just steal an ebook and give it a shot? If you "really like the premise" half an hour of reading a bit of the first one to see if you like it won't kill you - especially since this series doesn't really dive head first into the shitter with later volumes like a few others of its genre did.
I for one really liked them, they're light, popcorn-y books, but then I don't give a shit about the elitist trolls 'round these parts. If it feels good, man, I read it.
