Ah, 'Darling'—that title always makes me pause because there are a few books with similar names floating around! The one I think you might mean is the psychological thriller by Jessica Anthony, which came out in 2020. It’s this eerie, fragmented love story about a couple’s toxic relationship, told through texts, photos, and ephemera. Super unique format—like piecing together a mystery. Jessica’s background in visual art really shines through in how she constructs the narrative. If you’re into experimental storytelling, it’s a wild ride.
That said, there’s also K. Ancrum’s 'Darling,' a YA reimagining of 'Peter Pan' with a dark, sapphic twist. Totally different vibe but equally gripping. Ancrum has this way of weaving folklore into modern settings that feels fresh. I devoured it in one sitting—the tension between Wendy and Peter is electric. So yeah, depends which 'Darling' you’re after! Both are worth checking out, though.
