Hell's Heart by Alexis Hall

Gideon the Ninth meets Moby-Dick in USA Today bestselling author Alexis Hall's thrilling SF debut, Hell's Heart!

They are monsters, legends, gods.

They are our prey.

Earth is dead. Which leaves us stuck living in atmospheric domes on planets that will kill us if we blink wrong, or run out of fuel. And by “fuel” I mean “the cerebrospinal fluid of gargantuan, quasi-psychic space monsters”.

I joined the hunt hoping to get paid and maybe laid, but mostly paid. Instead, I followed a captain chasing abominations in the skies of Jupiter.

We battled the Möbius Beast itself, there in the red eye of the world.

Spoiler: we lost.
