thread tl;dr and I'm lazy
OP:
I like me some Amelia Atwater-Rhodes novels. Sure, they're at a sixth grade reading level, but they're still good timefillers. She writes mainly vampire and shapeshifter stuff. Lately I've been reading the Montmorency series by Eleanor Updale. It's not what you asked for, but they're still pretty good. They're set in the late 1800s-early 1900s and the main character has kind of a Jekyll-and-Hyde thing going on.
