Summerland is a magical place, where the local Little League gathers to play baseball on a perfectly manicured lawn, and the sun is always shining in a flawless blue sky. However, the small beings known as ferishers, who ensure this perfect weather, are threatened by an ancient enemy and need a hero-a baseball star, in fact-to vanquish their foe.

The ferishers recruit Ethan Feld, possibly the worst ballplayer in the history of the league, as their chosen leader. No one is more surprised than Ethan at their choice, but their faith spurs him on.

Accompanied by his determined friend Jennifer T. Rideout and a motley crew of creatures that includes everything from a Sasquatch to a werefox, Ethan struggles to defeat giants, bat-winged goblins, and one of the toughest ball clubs in the realms of magic to save the Summerlands, and, ultimately, the world.

Michael Chabon, one of the most acclaimed storytellers of our time, creates a whole new universe richly drawn from American folklore, with legendary beings, monsters, and mythical creatures inhabiting a magical landscape where the powers of the past and the future, of good and evil, are locked in grand battle.
