w Alex Garner, Jeff Mariotte; a Gabriel Hernandez, Mindy Lee).
[From IDW: American intelligence services have a secret weapon—and
it has fangs! This volume collects the original graphic novella by Alex
Garner and Mindy Lee that introduced CVO—vampire operatives who spy
for the United States, dealing with the most dangerous global threats—plus
CVO Artifact, by Jeff Mariotte and Gabriel Hernandez, the spine-tingling
tale of an incredibly ancient artifact and a disappearing colleague that
lead CVO toward an encounter with a deadly trio.] 
CVO: Rogue State (5-issue mini? + CVO: Human Touch?;
w Jeff Mariotte; a Antonio Vazquez). [From IDW: When
a mole in CVO exposes the whole organization to danger, things look bad
for America's first line of supernatural defense against growing global
threats. With fellow agents being killed all around them, the vampire spies
of CVO may find themselves out in the cold. A fast-paced combination of
horror and espionage, CVO is already in development by Konami as a major
video game.]
