When the Samhain wind blows, the veil between the worlds grows thin...

The Pattersonville West High School Unicorns have finally won the State Championship. But a surprise visit from their Fairy Realm neighbors during their celebrations brings a unique invitation for the mortal champions to play in the upcoming Fall Season.

Star players Emily DeWitt and Adrien Thorn have learned hard lessons about dealing with fairy lords, but they can't convince their excitable Unicorn teammates to decline. Even Benji Amberman, the spiderkin-descended caretaker of the fabulous Web Gem, wants to play, noting that Samhain's approach makes traversing the fairy ring under Unicorn Field even easier.

Luckily, Adrien thinks he can ward Unicorn Field to keep the town safe. Callie McMasters, while still tied to the Wild Hunt, is on board to help. But getting Emily to join is going to be easier said than done because Emily intends to sit the entire season out.

Meanwhile, Megan Moore, intrepid freelance reporter, sees a chance at the scoop of a lifetime.

But Benji finds they may have bitten off more than they can chew.

If they can't strengthen their control of the Web Gem, the Fall Season might destroy Benji and leave Pattersonville exposed to the most power-hungry denizens of the Fairy Realm.
