This is the book in the middle of Freaky Friday and Summer Switch, that I didn't know existed . It's a cute time travel plot where Ape Face fixes a TV that then gets the news from tomorrow, Boris tries to use it to make money, and Annabel worries about how to stop disasters she knows are going to happen.

The big denouement is a bit saccharine and uncomfortable... Boris has thrown away his mother's life and made over the apartment, and then she lectures him about how he doesn't know what's best for her, and he should accept her the way she is, and they all sob and say they love each other. It's a bit weird in a parent/child relationship... ( )

A boy's invention makes him a billion dollars.
