From the moment Horace F. Andrews sees the sign from the bus—a sign with his own name on it—everything changes. The sighting leads him underground, to the House of Answers, a hidden warehouse full of mysterious objects. But there, he finds only questions. What is this curious place? Who are the strange, secretive people who entrust him with a rare and immensely powerful gift? And what is he to do with it?
When Horace finds the Box of Promises in the curio shop, he quickly discovers that ordinary-looking objects can hold extraordinary power. From the enormous, sinister man shadowing him to the gradual mastery of his newfound abilities to his encounters with Chloe—a girl who has an astonishing talent of her own—Horace follows a path that puts the pair in the middle of a centuries-old conflict between two warring factions in which every decision they make could have disastrous consequences.
