If Abby refusing to abandon Gretchen—even after the tapes, the cafeteria incident, and that disastrous exorcism—was what gripped you, you’ll click with the bonds on Sawkill Island. Marion, Zoey, and Val are tangled in rivalries and painful secrets while a predatory presence takes girls one by one. Like Abby’s ride-or-die determination, their alliances sharpen into a weapon, and the horror hits close: missing friends, whispered legends, and girls who decide to save one another when adults won’t.

If you cackled at the mall-rat banter and the chaotic aerobics-tape exorcism with Christian Lemon—then immediately winced at scenes like the worm diet and the locker-room horrors—this nails that same tightrope. Patricia’s genteel book club faces a charming monster who preys on her neighborhood, and the PTA politics and casserole-night comedy collide with gnarly, unforgettable set pieces. It’s that same Hendrix alchemy of friendship, gallows humor, and oh-no-they-didn’t escalation you loved in My Best Friend’s Exorcism.

If Gretchen’s spiraling behavior had you toggling between demon and trauma—while Abby tried to parse the truth—you’ll be hooked by Merry and Marjorie’s story. A reality-TV exorcism, a skeptical priest, and a family unraveling in real time mirror that unsettling ambiguity from My Best Friend’s Exorcism. The sisters’ bond carries the dread, just like Abby’s loyalty to Gretchen, and the question lingers: what’s really possessing this house?

If what terrified you was Abby watching Gretchen change room by room—whispers in the dark, a best friend turning into a stranger—Blatty’s classic traps you in a Georgetown townhouse with Chris and her daughter, Regan. The close-quarters dread, tense interrogations of faith, and the desperate arrival of a priest echo the most nerve-scraping beats of My Best Friend’s Exorcism, only distilled to pure, relentless intensity.

If the toxic-clique pressure around Gretchen—and the way belief turns into a weapon—stuck with you, this YA shocker doubles down. Sofia falls in with Riley’s glittering mean-girl circle, and a basement “exorcism” aimed at a classmate spirals into brutality. Like Abby’s ordeal, it’s teen-girl dynamics under a magnifying glass: rumor, righteousness, and the terror of realizing the real monsters might be in your friend group.
