Studios, with all three installments collected into a stand-alone graphic novel entitled Zombie Tales 2061 in mid-2009. This led to an appearance at the 2009 Los Angeles Times Festival of Books, where she along with Chip Mosher, Michael Alan Nelson, Gary Philips and Mark Waid participated in "Big! Bold! BOOM!: BOOM! Studios Talks Comics," discussion, which was moderated by Los Angeles Times writer Geoff Boucher.
