Children of the Red King #2: Charlie Bone and the Time Twister

by Trenton Lee Stewart

Stewart crafts that same blend of puzzle-box plotting and found-family dynamics that makes Nimmo's work so addictive—you've got gifted kids discovering their abilities while navigating a mystery that unfolds in layers. The pacing has that same page-turning quality where you're never quite sure what the rules of the world are until the author reveals them, and the humor lands without undermining the genuine stakes.

by John Bellairs

Published in 1973, this is a masterclass in atmospheric children's fantasy that predates Nimmo but shares her gift for making old houses feel genuinely alive with secrets. Bellairs writes with this wonderful creeping dread—the clock ticking toward something terrible—while keeping the emotional core centered on a lonely kid finding belonging. The time-manipulation element in your recent read would feel like a natural echo here.

by Diana Wynne Jones

Jones has that same playful approach to magic systems that Nimmo does—where the rules are internally consistent but delightfully weird—and her dialogue crackles with personality in ways that make you want to reread conversations. The story jumps between timelines and realities in a way that echoes the time-twisting mechanics you just read, but filtered through a completely different emotional register: wry, romantic, and genuinely funny rather than spooky.

by George MacDonald

Here's your surprise pick: this reads almost like literary fantasy—it's quieter and more introspective than Nimmo's work, focused on character development and court politics rather than action sequences. But if you loved the way Charlie Bone navigates a world of hidden rules and dangerous relatives, you'll find that same tension here, just expressed through dialogue and observation rather than magical confrontations. It's proof that fantasy can be contemplative and still absolutely gripping.

by Jonathan Stroud

Stroud structures his magic system around objects of power the way Nimmo does with the marble—small, concrete things that unlock larger mysteries—and he's got that same gift for making London feel like a character itself, layered with hidden magical infrastructure. The dual-perspective narrative (jumping between characters) gives you more puzzle pieces to assemble, and the pacing builds with the same relentless momentum that made Time Twister so hard to put down.
