Julian used to be a ghost and now he can't stop seeing them.
Ever since being sacrificed as part of a forbidden ritual, Julian has been able to see and communicate with the spirits of passed brujx. And that would be okay, if it allowed him to be part of his new boyfriend's community. But Julian's also seeing other things: shadows in the corner of his eyes, glowing eyes in the dark, and "dark spots" on people – gaping, black gashes that are somehow wrong. He did ask his new magical boyfriend about it, but Yadriel has never heard of anything like it either, and he's so busy with his new Brujx responsibilities, trying to figure out where all the new malingos are coming from, that Julian hates for his problems to ruin what little time together they have.
Then, a strange new brujx shows up. Ángel, as a nonbinary brujx, can heal the living and release the dead, but more than that, they can also see the same dark spots as Julian. Despite Yadriel's reservations, Julian eagerly accepts their help. But, Ángel's ruthless methods feel wrong to Julian, who wants to move away from hurting others.
With the shadows growing darker, and the discovery of a gaping dark spot on his friend Luca, Julian has to decide who he wants to put his trust in, and just how far he's willing to go to save what is his.
