Henry thinks he is the King of Dweebs. He wants to escape. He wants to be?
Well maybe that's the problem he doesn't know what else to be or how to get there. A hornless unicorn takes him to a land called Altara.
In Altara, Henry will meet his identical other, discover he is the real heir to rule Altara and try not to get killed. He also finds a fire in his gut. He finds out what it is to be alive. His greatest challenge is to sustain that fire in middle school where he feels he is suffocating. Where he will play coach in two chess matches, go to his first dance, have his first middle school romance (and break up) and face the impossible challenge of climbing the rope hanging from the gym ceiling.
Stuart weaves together the two worlds and the life of Henry and his identical other into 12 days of very realistic living. By the end Henry knows who he is. He knows what it means to be Henry on Fire living in suburbia.
