New York City is experiencing the hottest summer on record. Eleven-year-old Arcade Livingston can't keep his cool after receiving this suspicious warning atop the Empire State Building: Things will heat up in all areas to test your mettle. In no time flat, Arcade is tested like never before to use the Triple T token's powerful ways to outsmart a bully, find a place for his best friend to live, and spy on some pesky villains from the 1900s. Meanwhile, sister Zoe thinks controlling the token is nothing but a path to disaster. One thing's for sure, the token continues its flashing and pulsing. And elevator doors continue to transport Arcade, Zoe, and their friends to meet different people in strange locations-people who challenge them, teach them, and inspire them to grow in patience and compassion. And just as a trip through a fiery furnace is necessary to purify gold, the token leads Arcade through superheated situations to test the purity of his heart.
