Switch #1 is the best Witchblade/Darkness story I've ever read. It sets up the new possessor of the Witchblade, Mary, really well, and intriguingly world-builds the Witchblade/Darkness/Angelus mythology without anyone having to know backstory while dropping Easter eggs for those who do. And it ends on a great cliffhanger. Stjepan Sejic was always a terrific artist, but with this and Sunstone, he's really shown he's a terrific writer as well.
