Felix is spending his last summer in Costa Rica - where continents meet and oceans part. At the very center of global crossroads- he faints and falls through the divide. When he wakes- he's in an upside-down dimension - mythical beasts are real- humans are imaginary. To find his way home- Felix will need the help of his new friend - Betony- a spunky elfin girl; and Ironclaw- an eagle-eyed creature who's mad for math! Just maybe- with a little magic- they can also help Felix find a cure for his diseased heart!
