The teagarden mysteries and the lily bard mysteries are nothing like true blood, very normal world type stuff. The ...Harper Connelly series (I finally remembered it!) that has grave sight does have the spooky but it's just sort of like ghost esp, no other supernatural bogies.

I have a sony e reader as well (t650) I just don't have room for hard copy books in this tiny place and already have a ton of them. Let me know how you like the books when you've read them!
