Is there a book series that you're not totally into, but still keep buying new releases because you love the covers?Um...no. I can't say that there's a series I keep buying because of the covers. I do have a few that I'm not into as much but I keep buying because I'm invested in the series by now. The Sookie Stackhouse (Southern Vampire) novels, for one, and the Stephanie Plum novels is another. I do still enjoy the books, just not on the same scale as the originals. I'm just "meh" about them at this point.
I will pick up a first book based on the cover, but if it doesn't hold my interest, no matter how good the cover of future books (example: the Luxe series), I'm over it. I'd rather save my money to buy something good.
