Kimberly Frost's Southern Witch Novels have amazing covers. I can't decide which one I like better, I fell in love with the first one, but Halway Hexed is is just so spectaular up close that I just don't know.. :)Charlaine Harris always has cool cartoon covers and this anthology
she edited is another hit. I might even like it more than the rest.
Chris Moore has hilarious novels and his covers are always witty and eye catching as well.
