Dan dos Santos is an artist (check out his gallery) who makes a lot of awesome covers for urban fantasy, fantasy and science fiction books, f.e.
Diana Rowland's My Life as a White Trash Zombie,
Richard Kadrey's Butcher Bird,
Gini Koch's Alien in the Family, as well as
Patricia Briggs' Mercy Thompson and Alpha & Omega series.
The latter is one of my favorite authors and here Dan dos Santos describes the making of the newest cover in the last installment of Anna and Charles (Alpha & Omega #3), called Fair Game. The insight to the process is fascinating as always.
Here's the end result:
I adore this cover (though the first one would also have been amazing), it's so bold, rich and beautiful. Out of hundreds of books on a shelf, I'd pick this one up first.
