Amazon UK have added images for two upcoming releases in the UK: Wings by Aprilynne Pike and The Forest of Hands and Teeth by Carrie Ryan. Both are very different to their original US covers, especially the one for Wings.
Do you like them? TFOHAT is pretty cool, but I'm not keen on Wings. I think it makes it look quite young. Anyway, the good news is that they're both published over here soon, in April (Wings) and July (TFOHAT) respectively.
