I was at Amazon UK’s website and these covers for Patricia Briggs’ Mercy Thompson series came up (Orbit’s releasing them in the UK later this year):
Here are the original US covers:
I think the UK covers are more atmospheric than the US ones, but the US ones would grab my attention while I’m browsing in a bookstore. I think I just like colour!
The UK ones are quite good though – I like the silhouette-style concept and they do convey “urban fantasy” quite well. Also, it’s immediately obvious that they’re part of the same series. But – and especially in the “Iron Kissed” cover – doesn’t the girl strike you as just a tad bit too skinny?
