Warlord of Mars #19

In "Worms of Mars Part 1," John Carter and his allies face a dire threat as the First Born resist the death of Issus, and tensions flare when Tars captures noble women—only for John to release them, earning the trust of Linea. She warns them that the high priest of Issus is about to activate a planet-killing machine, setting off a race to stop it before Barsoom's atmosphere is drained. Written by Arvid Nelson and illustrated by Stefano Martino, with colors by Kyle Ritter and letters by Marshall Dillon, the cover by Joe Jusko captures the grim urgency of the moment.
