Time to link up with the Broke and the Bookish again!
I found this topic really hard. Covers play a big part in whether or not I read a book, so the awful ones tend to go back on the shelf. My general approach is "If I would be embarrassed to read this book in public, NOPE". So there are a few generalisations in here, because there are some books that sound really interesting but I just can't bring myself to read them based on the covers.
1. Lair of Dreams by Libba Bray
2. Polymer by Sally Rogers-Davidson
3. The US covers of the Discworld series by Terry Pratchett
4. Any movie tie-in cover
Look, I get that it helps sell the book, because people go and see the movie and then when they see the book with the matching cover they decide to read it. But in my opinion? It has a serious impact on your enjoyment of the book, because the cover forces you to constantly compare it to the movie, the way the characters were portrayed and the actors who played them.
5. Android Karenina by Ben H. Winters
6. Pretty much anything by Simon R. Green (except the Nightside series)
7. Broken by Kelley Armstrong
9. Any cover featuring a shirtless man whose head has been chopped off at the top.
You know the ones I mean. They're often black and white, and about 90% abs. They're increasingly prevalent in chick lit and new adult books, especially in the e-book editions. You may as well just write "SEXY TIMES AHOY!!" in giant letters on the cover and be done with it. The same goes for the Two People Almost Kissing covers.
10. The Ellie Chronicles by John Marsden
Which covers would you redesign?
