Crypt-City of the Deathless One

Ed Garth is the only man who ever walked out of the Black Forest of Ganymede, and the only man it broke. He returned from the crypt-city with no memory of what happened inside, only with a hollow guilt that haunts his nights and a fortune he cannot explain. Now two strangers have hired him to lead them back. They want what lies buried in that alien necropolis. Garth knows he should refuse. But something calls to him from those forgotten tunnels, some piece of himself he left behind. As they descend into the crystalline death-city, Garth must confront not just the alien horror that waits in the dark, but the possibility that the man he was before might have done things too terrible to remember, and that the man he is now might be worse. Kuttner weaves cosmic dread with sharp, economical prose, building a story where the real monster isn't some deathless ancient, but the guilt we carry without knowing why.
