While hiking on the Continental Divide of Costa Rica, a young boy with a heart condition falls into a magical otherworld full of fantastical creatures.

Felix is back at school, but things aren't back to normal! Rhino, the class bully, snatches the mysterious Brandee lamp he'd kept from his last adventure (in BACK TO THE DIVIDE), and next thing you know, a djinn has taken Rhino hostage and is demanding that Felix return him home to the mystical, back-to-front world. But no sooner is the djinn's wish granted than Rhino escapes into the villainous protection of Skullcap, new chief nasty of the Japegrins....
