If you loved how Katie Chandler joins MSI to use her magic immunity to foil Spellworks and Phelan Idris—navigating staff meetings with Merlin, HR-level hexes, and enchanted office mishaps—then you’ll have a blast with The Rook. Myfanwy Thomas wakes up to run the Checquy, a government agency for the supernatural, where she juggles deadly conspiracies, snarky memos, and bureaucratic monster management. It’s that same secret-agency-in-plain-sight energy that made MSI so fun.

Enjoyed Katie’s dry, self-aware humor—the awkward elevator rides with Owen, trading quips with the gargoyle Sam, and defusing charm-laced PR disasters at MSI? First Grave on the Right gives you Charley Davidson, a grim reaper PI whose razor wit cuts through hauntings, clues, and chaos. The banter and comic timing land just like Katie’s as she keeps NYC’s magic from going off the rails.

If the whimsical side of MSI—Merlin popping into meetings, charm-laced cube farms, and Katie’s commonsense fixes for spell-snafus—made you smile, The Very Secret Society of Irregular Witches will feel like a hug. Mika Moon’s gentle magic helps a chaotic household of young witches become a family, with cozy mishaps and heart over spectacle, much like Katie turning corporate sorcery into something human.

If you were rooting for Katie and Owen’s shy, simmering chemistry while they unraveled corporate sabotage at MSI, Soulless delivers that same spark. Alexia Tarabotti’s no-nonsense pragmatism collides with Lord Maccon’s gruff charm as they unravel conspiracies in a world of vampires and werewolves. The witty repartee and romantic tension mirror Katie and Owen’s dynamic—just with extra parasols and propriety.

If Katie’s competence—spotting glamours no one else can, keeping MSI from falling for Spellworks’ tricks, and backing up Merlin and Owen—won you over, Heroine Complex brings that same energy. Evie Tanaka starts as the put-upon assistant in a San Francisco superhero scene, then grows into her power while wrangling demonic cupcakes, viral chaos, and messy friendships. It’s the upbeat, capable-heroine arc you enjoyed with Katie.
