 Noah Body is loud, reckless, and completely imaginary. He's also the reason Josh spends so much time in detention. Whether he's starting food fights, hatching ridiculous schemes, or turning ordinary days into disasters, Noah always seems to find new ways to get Josh into trouble. 

 But when other kids' imaginary friends begin mysteriously disappearing, things stop being funny. Even worse, the children they belonged to don't remember them at all. It's as if those imaginary friends never existed. As the disappearances spread across town, Josh and Noah discover a trail of clues leading to the abandoned Wonder World Toys factory. Something is hiding there. Something that feeds on imagination. And with every passing day, Noah begins to fade. 

 Now Josh and Noah must work together to uncover the truth before it's too late. Because if they fail, Noah won't just disappear. Josh will forget he ever existed.
