Primordial HC, by Jeff Lemire

Mind-bending sci-fi collides with Cold War thriller in this six-issue series by the best-selling and Eisner-winning creative team behind GIDEON FALLS! In 1957 the USSR made history by launching a dog named Laika into Earth's orbit. Two years later the USA responded with two monkeys, Able and Baker. These animals never returned. But unbeknownst to everyone, they did not die in orbit… they were taken. And now they are coming home.
