If the way Anna’s house turned into a slaughterhouse and the Obeahman’s presence made your skin crawl, you’ll feel right at home with The Girl from the Well. Okiku is a vengeful spirit who hunts child-killers, and her encounters carry the same vicious, gore-tinged energy as Anna’s early rampage. Like how Anna shifts from monster to protector when Cas uncovers her curse, Okiku’s brand of justice becomes unexpectedly poignant as she aids Tark and Callie—delivering both chills and a surprising moral bite.

If you loved how Cas wisecracks his way through mortal danger—joking about his athame even as he’s ankle-deep in Anna’s house of horrors—Hold Me Closer, Necromancer hits the same nerve. Sam LaCroix narrates with that same gallows wit as he discovers he’s a necromancer and tangles with the predatory Douglas Montgomery. The blend of banter, sudden violence, and creeping dread mirrors Cas’s voice-as-armor vibe, right down to the "I’m in over my head but still cracking jokes" energy.

If the hush-hush mechanics of Cas’s life—tracking deaths, the athame’s rules, and sneaking into haunted spaces in Thunder Bay—hooked you, The Archived delivers that same urban-supernatural intrigue. Mackenzie Bishop patrols the Narrows to return restless "Histories" to the Library, a hidden archive of the dead. The locked doors, codes, and careful rituals echo Cas’s methodical hunts, while a converted hotel teems with the kind of dangers that turn ordinary hallways into places you’d rather not walk alone.

If Cas and Anna’s connection—starting with terror in her bloodstained house and deepening as he unravels her curse—kept you turning pages, The Dead and the Dark offers a similarly charged bond under supernatural pressure. As Logan and Ashley investigate disappearances in Snakebite, their relationship grows through danger, secrets, and the pull of a presence that’s as tragic as it is terrifying. It captures that same "love tangled with the dead" tension without losing the mystery’s bite.

If you tore through Cas’s quick, deadly confrontations—from the first showdown with Anna to the final clash with the Obeahman—The Screaming Staircase matches that pace. Lucy, Lockwood, and George take on high-risk hauntings armed with iron and nerve, and their investigations rocket from clue to catastrophe. The trio’s chemistry recalls Cas, Carmel, and Thomas braving cursed rooms and clever traps, delivering relentless set pieces that beg for one-more-chapter reading.
