There's something off about Spindlehollow.
The fog curls the wrong way. The candy shop sign is printed backwards. And Ziggy... well, Ziggy's acting different. She still rolls her eyes. She still throws sarcasm like confetti. But she forgot the name of their secret hideout-and she just winked with the wrong eye.
After finding a strange, full-length mirror in the forgotten basement of the Spindlehollow Library, Patches and Ziggy are pulled into a town that looks exactly like theirs... only darker, colder, and reflected.
As familiar faces begin to warp and Spindlehollow starts mimicking the mirror version piece by piece, Patches suspects something deeper is happening-and soon discovers that Ziggy was replaced before the adventure even began.
Now, with time (and reflections) running out, Patches must outwit the mirror's lies, rescue the real Ziggy from a world of twisted opposites, and stop the mirror town from replacing Spindlehollow completely.
Because sometimes, the greatest trick isn't what a mirror shows you-it's what it hides.
