The series is set in a magical land called Xanth (I believe it’s from the second “syllable” in Piers Anthony’s name). The map strongly resembles Florida, his home state.
Book 1, A Spell For Chameleon, introduces us to Bink, a young man who seems to have no magical talent. Everyone in Xanth must show they have magical ability by age 25, so he’s up for deportation to Mundania, a land without magic. Bink goes on a long and involved quest to see if he has a magical talent (for those who love HEA, everything ends well, but people who have reread the book much more recently than I have reservations about some story elements).
I want to mention Anthony’s other series that I love much more than the Xanth novels. You will not regret checking out the Apprentice Adept series that begins with Split Infinity and the Incarnations of Immortality starting with On a Pale Horse.
