Key passages

  • The figure beside me seemed less like a lifelong friend than like some monstrous intrusion from outer space—some damnable, utterly accursed focus of unknown and malign cosmic forces.

    The person next to me felt like a terrifying alien being rather than my old friend.

    Upton's visceral reaction to Derby's transformed state.

  • She had sensed the mixture of fine-wrought brain and weak will in him. Some day she would crowd him out and disappear with his body—disappear to become a great magician like her father and leave him marooned in that female shell that wasn't even quite human.

    She recognized his intelligence and weak will, planning to take over his body permanently and abandon him in her own inhuman form.

    Derby's explanation of Asenath's long-term plan for body-swapping.

  • I saw a shoggoth—it changed shape—I can't stand it—I'll kill her if she ever sends me there again—I'll kill that entity—her, him, it—I'll kill it! I'll kill it with my own hands!

    I witnessed a shape-shifting shoggoth and I will murder Asenath if she forces me to return to that place.

    Derby's hysterical outburst after being rescued from the occult pit.
