Book Review - Is This a Science Fiction Intervention?

Theo is now a single dad. Has his wife, elissa, died two years earlier. And he is with his son, robin, who turns nine in the beginning of the book. As robin maybe gets worse, theo goes to this man courier to see if robin could participate and get maybe more positive brain waves from other people. He ends up getting the brain waves from his deceased mother. The premise of the book was inspired by my discovery of that decoted neurofedback procedure that you just described.
