Passionate and emotional, this is a book of speeches from Greta that pack a punch.  This is a record of speeches given by Greta but not a book in of itself.  I think for what it is, is impactful for those who read it, to give a sense of urgency and motivation to complete your own research and possibly political rebellion.  But it is just a summary of spearhead it has not been written as a book, as it is repetitive, lacks narrative and lacks actionable steps.  I also think it will not be picked up by anyone who is not already sympathetic with Greta or the cause which means this will have little impact.  However I think this or a few of her speeches in general could be great to give as readings to schools/colleges and businesses to motivate a change in attitude.
