Rachel Caine, author of The Morganville Vampires series, has posted the UK Carpe Corpus cover on her LJ. Allison & Busby, the UK publishers, have also posted it on their site here, along with a synopsis.
I love it! The new style is brilliant, and I hope they re-release books 1-4 sometime soon. Carpe Corpus is released in the UK on 12th October, 2009 (according to Amazon).
