"Earthdivers created by Stephen Graham Jones and Davide Gianfelice."

"Originally published as Earthdivers #1-6"--Title page verso.

"The year is 2112, and it's the apocalypse exactly as expected: rivers receding, oceans rising, civilization crumbling. Humanity has given up hope, except for a group of Indigenous outcasts who have discovered a time travel portal in a cave in the desert and figured out where everything took a turn for the worst: America. Convinced that the only way to save the world is to rewrite its past, they send one of their own--a reluctant linguist named Tad--on a bloody, one-way mission to 1492 to kill Christopher Columbus before he reaches the so-called New World. But there are steep costs to disrupting the timeline, and taking down an icon isn't an easy task for an academic with no tactical training and only a wavering moral compass to guide him. As the horror of the task ahead unfolds and Tad's commitment is tested, his actions could trigger a devastating new fate for his friends and the future"--,Provided by publisher.
