Xanth
Piers Anthony's Xanth is high fantasy built almost entirely around wordplay, a magical peninsula where every citizen has a unique talent and where puns are not jokes but the literal building blocks of reality. The series runs long and light, more comic and episodic than epic, with each book sending a new protagonist on a quest through familiar territory.
This run lands mid-series, with entries like Ogre, Ogre, Night Mare, and Crewel Lye, by which point the world's rules and recurring figures are well established. Xanth is divisive on purpose: readers either delight in its relentless, groan-inducing humor or bounce off it entirely. What it offers consistently is invention, a setting that treats language itself as the deepest magic.
The Xanth franchise spans 7 books in the CrossBinge catalog.
